A

Acceptable Early Days

An item attribute the planning process uses to decide when to suggest rescheduling orders for the item to an earlier date. The planning process only suggests rescheduling orders for the item if the order is due to be received into inventory before the acceptable early date. This attribute is used when it is more economical to build and carry excess inventory for a short time than it is to reschedule the order. This attribute applies to discretely planned items only. The attribute for repetitively planned items is Overrun Percentage

Acceptable Rate Decrease

An item attribute the planning process uses to decide how much to decrease current daily rates for the item inside the planning time fence. The planning process does not suggest a new daily rate less than the current daily rate minus the acceptable rate decrease amount. If you do not define a value for this attribute, the planning process assumes that there is no lower limit to the new daily rate it can suggest for the item inside the planning time fence. If you set this attribute to zero, the planning process assumes it cannot suggest any rate less than the current daily rate inside the planning time fence. Inventory defaults the value of this attribute to zero. This attribute lets you minimize short term disruption to shop floor schedules by restricting short term rate change suggestions. This attribute applies to repetitively planned items only.

Acceptable Rate Increase

An item attribute the planning process uses to decide how much to increase current daily rates for the item inside the planning time fence. The planning process does not suggest a new daily rate that is greater than the current daily rate plus the acceptable rate increase amount. If you do not define a value for this attribute, the planning process assumes there is no upper limit to the new daily rate that it can suggest for the item inside the planning time fence. If you set this attribute to zero, the planning process assumes it cannot suggest any rate greater than the current daily rate inside the planning time fence. Inventory defaults the value of this attribute to zero. This attribute lets you minimize short term disruption to shop floor schedules by restricting short term rate change suggestions and applies to repetitively planned items only.

accounting period

The fiscal period a company uses to report financial results, such as a calendar month or fiscal period.

action message

Output of the MRP process that identifies a type of action to be taken to correct a current or potential material coverage problem.

action result

A possible outcome of an order cycle action. You can assign any number of results to a cycle action. Combinations of actions/results are used as order cycle action prerequisites. See also order cycle, cycle action.

actual demand

The demand from actual sales orders, not including forecasted demand.

aggregate repetitive schedule

The sum of detail schedules for an item across all work in process manufacturing lines in terms of a daily rate, and a start and end date.

aggregate resources

The summation of all requirements of multi-department resources across all departments that use it.

anchor date

The start date of the first repetitive planning period. It introduces consistency into the material plan by stabilizing the repetitive periods as time passes so that a plan run on any of the days during the first planning period does not change daily demand rates.

append option

Option or choice to append planned orders to an MRP plan or an MPS plan during the planning process. Append either after the last existing planned order, after the planning time fence, or for the entire plan. The append option is used with the overwrite option. See overwrite option

application building block

A set of tables and modules (forms, reports, and concurrent programs) that implement closely-related entities and their processing.

automatic rescheduling

Rescheduling done by the planning process to automatically change due dates on scheduled receipts when it detects that due dates and need dates are inconsistent.

available capacity

The amount of capacity available for a resource or production line.

B

backward consumption days

A number of days backwards from the current date used for consuming and loading forecasts. Consumption of a forecast occurs in the current bucket and as far back as the backward consumption days. If the backward consumption days enters another bucket, the forecast also consumes anywhere in that bucket. When loading a forecast, only forecasts of the current date minus the backward consumption days are loaded. Therefore, you can use backward consumption days to load forecasts that are past due.

base model

The model item from which a configuration item was created.

bill of distribution

Specifies a multilevel replenishment network of warehouses, distribution centers, and manufacturing centers (plants).

bill of material

A list of component items associated with a parent item and information about how each item relates to the parent item. Oracle Manufacturing supports standard, model, option class, and planning bills. The item information on a bill depends on the item type and bill type. The most common type of bill is a standard bill of material. A standard bill of material lists the components associated with a product or subassembly. It specifies the required quantity for each component plus other information to control work in process, material planning, and other Oracle Manufacturing functions. Also known as product structures.

bill of resource set

A group of bills of resources. A bill of resource set can have one or many bills of resources within it.

bill of resources

A list of each resource and/or production line required to build an assembly, model, or option.

bill-to address

The customer's billing address. It is also known as invoice-to address. It is used as a level of detail when defining a forecast. If a forecast has a bill-to address associated with it, a sales order only consumes that forecast if the bill-to address is the same.

bucket days

The number of workdays within a repetitive planning period.

C

Calculate ATP

An item attribute the planning process uses to decide when to calculate and print available to promise (ATP) for the item on the Planning Detail Report. The planning process calculates ATP using the following formula:
ATP = Planned production - committed demand.

capacity modification

Deviation to available resources for a specific department shift.

capacity requirements planning

A time-phased plan comparing required capacity to available capacity, based on a material requirements plan and department/resource information. See routing-based capacity and rate-based capacity

carry forward days

A number of days shifted forward (or backward when using a negative number) when copying a forecast into another forecast or a master schedule into another master schedule. The load process shifts any entries on the source forecast (or schedule) onto the destination forecast (or schedule) forward or backward by this many days.

chase production strategy

A production strategy that varies production levels to match changes in demand. This production strategy results in minimal inventory carrying costs at the expense of fluctuating capacity requirements.

component demand

Demand passed down from a parent assembly to a component.

component item

An item associated with a parent item on a bill of material.

component yield

The percent of the amount of a component you want to issue to build an assembly that actually becomes part of that assembly. Or, the amount of a component you require to build plus the amount of the component you lose or waste while building an assembly. For example, a yield factor of 0.90 means that only 90% of the usage quantity of the component on a bill actually becomes part of the finished assembly.

compression days

The number of days the planning process suggests you compress the order (in other words, reduce the time between the start date and the due date).

concurrent manager

Components of your applications concurrent processing facility that monitor and run time-consuming tasks for you without tying up your terminal. Whenever you submit a request, such as running a report, a concurrent manager does the work for you, letting you perform many tasks simultaneously.

confidence percent

The degree of confidence in a forecast that the forecasted item becomes actual demand. When loading schedules from a forecast, the confidence percent is multiplied by the forecast quantity to determine the schedule quantity

configuration item

The item that corresponds to a base model and a specific list of options. Bills of Material creates a configuration item for assemble-to-order models.

CRP planner

A process that may optionally be run as part of the planning process. The CRP planner calculates capacity requirements for resources and production lines using the material requirements calculated by the planning process.

current aggregate repetitive schedule

The sum of all current work in process repetitive schedules for an item for all lines for a given period in terms of a daily rate, and a start and end date. Current aggregate repetitive schedules can be firm or partially firm. If all current repetitive schedules for an item are firm, then the current aggregate repetitive schedule for the item is also firm. If some, but not all the current repetitive schedules for an item are firm, then the current repetitive schedule is partially firm.

current date

The present system date.

current projected on-hand

Quantity on-hand projected into the future if scheduled receipts are not rescheduled or cancelled, and new planned orders are not created as per recommendations made by the planning process. Calculated by the planning process as current supply: (nettable quantity on hand + scheduled receipts) - gross requirements. Note that gross requirements for projected on hand does not include derived demand from planned orders. Note also that the planning process uses current due dates rather than suggested due dates to pass down demand to lower level items. See projected available balance

cutoff date

An indication of the last date to be included in a plan or horizon.

D

daily rate

The number of completed assemblies a repetitive schedule plans to produce per day. Also known as production rate. See repetitive rate

database diagram

A graphic representation of application tables and the relationships among them.

deliver-to location

A location where you deliver goods previously received from a supplier to individual requestors.

demand class

A classification of demand to allow the master scheduler to track and consume different types of demand. A demand class may represent a particular grouping of customers, such as government and commercial customers. Demand classes may also represent different sources of demand, such as retail, mail order, and wholesale.

demand management

The function of recognizing and managing all demands for products, to ensure the master scheduler is aware of them. This encompasses forecasting, order entry, order promising (available to promise), branch warehouse requirements, and other sources of demand.

Demand Time Fence

Item attribute used to determine a future time inside which the planning process ignores forecast demand and only considers sales order demand when calculating gross requirements for an item. Use this attribute to identify a time fence inside which you wish to build to sales order demand only to reduce the risk of carrying excess inventory. A value of Cumulative manufacturing lead time means Master Scheduling/MRP calculates the demand time fence for the item as the plan date (or the next workday if the plan is generated on a non workday) plus the cumulative manufacturing lead time for the item. A value of Cumulative total lead time means Master Scheduling/MRP calculates the demand time fence for the item as the plan date (or the next workday if the plan is generated on a non workday) plus the total manufacturing lead time for the item. A value of Total lead time means Master Scheduling/MRP calculates the demand time fence for the item as the plan date (or the next workday if the plan is generated on a non workday) plus the total lead time for the item. A value of User-defined time fence means Master Scheduling/MRP calculates the demand time fence for the item as the plan date (or the next workday if the plan is generated on a non workday) plus the value you enter for Planning Time Fence Days for the item.

Demand Time Fence Days

Item attribute used when you set the Planning Time Fence attribute to User-defined time fence. Master Scheduling/MRP calculates the demand time fence for the item as the plan date (or the next workday if the plan is generated on a non workday) plus the value you enter here.

department

An area within your organization that consists of one or more people, machines, or suppliers. You can also assign and update resources to a department.

dependent demand

Demand for an item that is directly related to or derived from the demand for other items.

destination forecast

The forecast you load into when copying a forecast into another forecast.

disable date

A date when an Oracle Manufacturing function is no longer available for use. For example, this could be the date on which a bill of material component or routing operation is no longer active, or the date a forecast or master schedule is no longer valid.

discrete job

A production order for the manufacture of a specific (discrete) quantity of an assembly, using specific materials and resources, in a limited time. A discrete job collects the costs of production and allows you to report those costs--including variances--by job. Also known as work order or assembly order.

dock date

The date you expect to receive a purchase order.

due date

The date when scheduled receipts are currently expected to be received into inventory and become available for use.

E

end assembly pegging

A Pegging item attribute option the planning process uses to decide when to calculate and print end assemblies for the item on the Planning Detail Report. Even if you do not select this option, you can still calculate and view end assemblies for the item on-line.

end date

Signifies the last date a particular quantity should be forecast on a forecast entry. From the forecast date until the end date, the same quantity is forecast for each day, week or period that falls between that time frame. An entry without an end date is scheduled for the forecast date only.

end item

Any item that can be ordered or sold. See finished good and product

engineering change order (ECO)

A record of revisions to one or more items usually released by engineering.

entity

A data object that holds information for an application.

exception message

A message received indicating a situation that meets your predefined exception set for an item, such as Items that are overcommitted, Items with excess inventory, and Orders to be rescheduled out.

exploder

The first of the three processes that comprise the planning process under the standard planning engine. The exploder explodes through all bills of material and calculates a low level code for each item. The low level codes are used by the planner to ensure that net requirements for a component are not calculated until all gross requirements from parent items have first been calculated. The exploder runs before the snapshot and planner. Under the memory-based planning engine, the memory-based snapshot performs exploder functions.

F

finished good

Any item subject to a customer order or forecast. See also product

firm planned order

An MRP-planned order that is firmed using the Planner Workbench. This allows the planner to firm portions of the material plan without creating discrete jobs or purchase requisitions. Unlike a firm order, a MRP firm planned order does not create a natural time fence for an item.

firm scheduled receipt

A replenishment order that is not modified by any planning process. It may be a purchase order, discrete job, or repetitive schedule. An order is firm planned so that the planner can control the material requirements plan.

Fixed Days Supply

An item attribute the planning process uses to modify the size and timing of planned order quantities for the item. The planning process suggests planned order quantities that cover net requirements for the period defined by the value you enter here. The planning process suggests one planned order for each period. Use this attribute, for example, to reduce the number of planned orders the planning process would otherwise generate for a discretely planned component of a repetitively planned item.

Fixed Lot Size Multiplier

An item attribute the planning process uses to modify the size of planned order quantities or repetitive daily rates for the item. For discretely planned items, when net requirements fall short of the fixed lot size multiplier quantity, the planning process suggests a single order for the fixed lot size multiplier quantity. When net requirements for the item exceed the fixed lot size multiplier quantity, the planning process suggests a single order with an order quantity that is a multiple of the fixed lot size multiplier quantity. For repetitively planned items, when average daily demand for a repetitive planning period falls short of the fixed lot size multiplier quantity, the planning process suggests a repetitive daily rate equal to the fixed lot size multiplier quantity. When average daily demand for a repetitive planning period exceeds the fixed lot size multiplier quantity, the planning process suggests a repetitive daily rate that is a multiple of the fixed lot size multiplier quantity.

fixed order quantity

An item attribute the planning process uses to modify the size of planned order quantities or repetitive daily rates for the item. When net requirements fall short of the fixed order quantity, the planning process suggests the fixed order quantity. When net requirements for the item exceed the fixed order quantity, the planning process suggests multiple orders for the fixed order quantity. For discretely planned items, use this attribute to define a fixed production or purchasing quantity for the item. For repetitively planned items, use this attribute to define a fixed production rate for the item. For example, if your suppliers can only supply the item in full truckload quantities, enter the full truckload quantity as the fixed order quantity for the item.

focus forecasting

A simulation-based forecasting process that looks at past inventory activity patterns to determine the best simulation for predicting future demand.

forecast

An estimate of future demand on inventory items. A forecast contains information on the original and current forecast quantities (before and after consumption), the confidence factor, and any specific customer information. You can assign any number of inventory items to the forecast and use the same item in multiple forecasts. For each inventory item you specify any number of forecast entries.

forecast consumption

The process of subtracting demand generated by sales orders from forecasted demand thereby preventing demand being counted twice in the planning period.

forecast date

The date for a forecast entry for an item. A forecast for an item has a forecast date and an associated quantity.

forecast demand

A part of your total demand that comes from forecasts, not actual sales orders.

forecast end date

A forecast end date implies that until that date, the same quantity is scheduled for each day, week, or period that falls between the forecast date and the end date. A forecast date with no forecast end date is the quantity for that particular day, week, or period, depending on the bucket size.

forecast end item

The parent item for components that receive exploded forecasts during forecast explosion. Used to identify the highest level planning or model item from which forecasts for a component can be exploded.

forecast entry

A forecast for an inventory item stated by a date, an optional rate end date, and quantity.

forecast explosion

Explosion of the forecast for planning and model bills of material. The forecasted demand for the planning or model bill is passed down to create forecasted demand for its components. You can choose to explode the forecast when loading a forecast.

forecast level

The level at which a forecast is defined. Also, the level at which to consume a forecast. Example forecast levels include items, customers, customer bill-to, and customer ship to locations.

forecast load

The process of copying one or more source forecasts into a single destination forecast. When copying forecasts, you can choose to overwrite all or a subset of existing entries in the destination forecast, specify whether to explode the source forecast, and specify whether to consume the source forecast. You can choose to modify the source forecast by a modification percent, or roll the source forecast forward or backward by a specified number of carry forward days. You can also load compiled statistical and focus forecasts from Inventory, and you can use the forecast interface table to load forecasts into Master Scheduling/MRP from external sources.

forecast set

A group of complementing forecasts. For each forecast set, you specify a forecast level, consumption use, update time fence days, outlier update percents, disable date, default time bucket and demand class. A forecast set can have one or many forecasts within it.

forward consumption days

A number of days forward from the current date used for consuming and loading forecasts. Consumption of a forecast occurs in the current bucket and as far forward as the forward consumption days. If the forward consumption days enters another bucket, the forecast consumes anywhere in that bucket, as well.

G

gross requirements

The total of independent and dependent demand for an item before the netting of on-hand inventory and scheduled receipts.

H

hard reservation

Sales order demand that you firm by reserving selected inventory for the purposes of material planning, available to promise calculations, and customer service issues.

I

independent demand

Demand for an item unrelated to the demand for other items.

internal requisition

See internal sales order, purchase requisition.

internal sales order

A request within your company for goods or services. An internal sales order originates from an employee or from another process as a requisition, such as inventory or manufacturing, and becomes an internal sales order when the information is transferred from Purchasing to Order Entry. Also known as internal requisition or purchase requisition.

J

K

L

lead time line

The production line Bills of Material uses to calculate the processing lead time for a particular repetitive assembly, since lead times may vary on different production lines.

level production strategy

A production strategy that maintains stable production levels despite changes in demand. The level production strategy results in minimal fluctuations in capacity requirements at the expense of additional inventory carrying costs.

line priority

The line priority indicates which production line to use to build assemblies. You create repetitive schedules on the highest priority line first, then, if the line capacity is less than demand, additional repetitive schedules are created on other lines in decreasing order of their line priority. For example, if demand is for 1000 units per day on two lines with a daily capacity of 750, the line with the highest priority is loaded with 750 and the lower priority line with 250. For lines of equal priority, the load is allocated evenly across lines.

line speed

The hourly production rate of assemblies on a production line.

load factor

The maximum hourly rate divided by the line speed for a given repetitive assembly and production line.

load rate

The required rate multiplied by the load factor for a given production line.

loader worker

An independent concurrent process in planning engine, launched by the snapshot monitor, that loads data from operating system files into tables.

low level code

A number that identifies the lowest level in any bill of material that a component appears. Low level codes are used by the MRP planner to ensure that net requirements for the component are not calculated until all gross requirements from parent items have first been calculated.

M

manual rescheduling

The most common method of rescheduling scheduled receipts. The planning process provides reschedule messages that identify scheduled receipts that have inconsistent due dates and need dates. The impact on lower level material and capacity requirements are analyzed by material planners before any change is made to current due dates.

master demand schedule

The anticipated ship schedule in terms of rates or discrete quantities, and dates.

master production schedule (MPS)

The anticipated build schedule in terms of rates or discrete quantities, and dates.

master schedule

The name referring to either a master production schedule or a master demand schedule. See master demand schedule and master production schedule

master schedule load

The process of copying one or more source forecasts, master schedules, or sales orders into a single destination master schedule. When copying forecasts, you can choose to include all or a subset of sales orders, specify whether to consider demand time fence, and specify whether to consume the source forecast during the load. You can also specify update options to control consumption of the source forecast during the load. When copying master schedules, you can choose to modify the source master schedule by a specified number of carry forward days. When loading sales orders, you can choose to load all or a subset of sales orders, and you can specify whether to consider the demand time fence during the load. You can use the master schedule interface table to load master schedules from external sources.

material requirements planning (MRP)

A process that utilizes bill of material information, a master schedule, and current inventory information to calculate net requirements for materials.

material scheduling method

During the planning process, the method used to determine when to stage material used in the production of a discrete job. You can schedule material to arrive on the order start date or the operation start date where a component is required.

Maximum Order Quantity

An item attribute the planning process uses to modify the size of planned order quantities or repetitive daily rates for the item. For discretely planned items, when net requirements exceed the maximum order quantity, the planning process suggests the maximum order quantity. For repetitively planned items, when average daily demand for a repetitive planning period exceeds the maximum order quantity, the planning process suggests the maximum order quantity as the repetitive daily rate. Use this attribute, for example, to define an order quantity above which you do not have sufficient capacity to build the item.

maximum rate

The maximum number of completed assemblies a production line can produce per hour.

minimum firm rate

The aggregate schedule that is partially firm since only some of the detail schedules are firm within a particular time frame

Minimum Order Quantity

An item attribute the planning process uses to modify the size of planned order quantities or repetitive daily rates for the item. For discretely planned items, when net requirements fall short of the minimum order quantity, the planning process suggests the minimum order quantity. For repetitively planned items, when average daily demand for a repetitive planning period falls short of the minimum order quantity, the planning process suggests the minimum order quantity as the repetitive daily rate. Use this attribute, for example, to define an order quantity below which it is not profitable to build the item.

minimum rate

The minimum number of completed assemblies a production line can produce per hour.

model bill of material

A bill of material for a model item. A model bill lists option classes and options available when you place an order for the model item.

modification percent

Used to modify the destination master schedule entries or forecast entries you are loading by a percent of the source entries.

module

A program or procedure that implements one or more business functions, or parts of a business function in an application. Modules include forms, concurrent programs, and subroutines.

MPS

See master production schedule.

MPS explosion level

An option for a master demand schedule that lets you limit the explosion through unnecessary levels during the MPS planning process. Set the explosion level to the lowest level on the bill of material that an MPS-planned item exists so the planning process does not need to search through all levels for MPS-planned items.

MPS plan

A set of planned orders and suggestions to release or reschedule existing schedule receipts for material to satisfy a given master schedule for MPS-planned items or MRP-planned items that have an MPS-planned component. Stated in discrete quantities and order dates.

MPS-planned item

An item controlled by the master scheduler and placed on a master production schedule. The item is critical in terms of its impact on lower-level components and/or resources, such as skilled labor, key machines, or dollars. The master scheduler maintains control for these items.

MRP

See material requirements planning.

MRP plan

A set of planned orders and suggestions to release or reschedule existing schedule receipts for material to satisfy a given master schedule for dependent demand items. Stated in discrete quantities and order dates.

MRP-planned item

An item planned by MRP during the MRP planning process.

multi-department resource

A resource whose capacity can be shared with other departments.

N

nervousness

Characteristic exhibited by MRP systems where minor changes to plans at higher bill of material levels, for example at the master production schedule level, cause significant changes to plans at lower levels.

net change simulation

Process used to make changes to supply and demand and re-plan them.

net requirements

Derived demand due to applying total supply (on-hand inventory, scheduled receipts, and safety stock quantities) against total demand (gross requirements and reservations). Net requirements, lot sized and offset for lead time, become planned orders. Typically used for rework, prototype, and disassembly.

O

option

An optional item component in an option class or model bill of material.

option class

A group of related option items. An option class is orderable only within a model. An option class can also contain included items.

option class bill of material

A bill of material for an option class item that contains a list of related options.

organization

A business unit such as a plant, warehouse, division, department, and so on. Order Entry refers to organizations as warehouses on all Order Entry windows and reports.

origination

The source of a forecast entry or master schedule entry. When you load a forecast or master schedule, the origination traces the source used to load it. The source can be a forecast, master schedule, sales order, or manual entry.

outlier quantity

The amount of sales order left over after the maximum allowable amount (outlier update percent) was used to consume a forecast.

outlier update percent

The maximum percent of the original quantity forecast that a single sales order consumes. It is used to limit forecast consumption by unusually large sales orders

overload

A condition where required capacity for a resource or production is greater than available capacity.

overrun percentage

An item attribute the planning process uses to decide when to suggest new daily rates for the item. The planning process only suggests a new daily rate for the item if the current daily rate exceeds the suggested daily rate by more than the acceptable overrun amount. This attribute lets you reduce nervousness and eliminate minor rate change recommendations when it is more economical to carry excess inventory for a short time than it is to administer the rate change. This attribute applies to repetitively planned items only. The related attribute for discretely planned items is Acceptable Early Days. See acceptable early days

overwrite option

Option to overwrite existing orders on an MRP plan or an MPS plan during the planning process. Without overwriting, you can keep your existing smoothed entries as well as add new ones. By overwriting, you erase the existing entries and add new one according to the current demand. The overwrite option in used with the append option. See append option

P

percent of capacity

The required hours divided by the available hours for any given department, resource, and shift combination.

period

See accounting period

pipe

Allows sessions in the same database instance to communicate with each other. Pipes are asynchronous, allowing multiple read and write access to the same pipe.

plan horizon

The span of time from the current date to a future date that material plans are generated. Planning horizon must cover at least the cumulative purchasing and manufacturing lead times, and is usually quite a bit longer.

planned order

A suggested quantity, release date, and due date that satisfies net item requirements. MRP owns planned orders, and may change or delete the orders during subsequent MRP processing if conditions change. MRP explodes planned orders at one level into gross requirements for components at the next lower level (dependent demand). Planned orders along with existing discrete jobs also serve as input to capacity requirements planning, describing the total capacity requirements throughout the planning horizon.

planned purchase order

A type of purchase order you issue before you order actual delivery of goods and services for specific dates and locations. You normally enter a planned purchase order to specify items you want to order and when you want delivery of the items. You later enter a shipment release against the planned purchase order when you actually want to order the items.

planner

The third of the three processes that comprise the planning process under the standard planning engine. The planner uses the low level codes calculated by the exploder, together with the supply and demand information gathered by the snapshot, and calculates net material requirements for every planned item associated with the master schedule used to drive the planning process. Under the standard planning engine, the planner runs after the exploder and the snapshot. Under the memory-based planning engine, the memory-based planner performs planner functions.

planner delete worker

An independent concurrent process, launched by the memory-based planner, that removes previous plan output from the tables. It runs only when the memory-based planner runs without the snapshot.

Planner Workbench

You can use the Planner Workbench to act on recommendations generated by the planning process for a plan. You can implement planned orders as discrete jobs or purchase requisitions, maintain planned orders, reschedule scheduled receipts, and implement repetitive schedules. You can choose all suggestions from an MRP plan, or only those that meet a certain criteria.

planning bill of material

A bill of material for a planning item that contains a list of items and planning percentages. You can use a planning bill to facilitate master scheduling and/or material planning. The total output of a planning bill of material is not limited to 100% (it can exceed this number by any amount).

planning exception set

A set of sensitivity controls used to define exceptions in your plan. You define the exception set according to your selected criteria and then report on exceptions that meet those criteria. You can assign an exception set to an item.

planning horizon

The amount of time a master schedule extends into the future.

planning manager

A process that performs once-a-day and period maintenance tasks. These tasks include forecast consumption, master schedule relief, forecast and master schedule loads, and other miscellaneous data cleanup activities.

planning process

The set of processes that calculates net material and resource requirements for an item by applying on-hand inventory quantities and scheduled receipts to gross requirements for the item. The planning process is often referred to as the MPS planning process when planning MPS-planned items only, and the MRP planning process when planning both MPS and MRP-planned items at the same time. Maintain repetitive planning periods is another optional phase in the planning process.

Planning Time Fence

A Master Scheduling/MRP item attribute used to determine a future point in time inside which there are certain restrictions on the planning recommendations the planning process can make for the item. For discretely planned items, the planning process cannot suggest new planned orders for the item or suggest rescheduling existing orders for the item to an earlier date. For repetitively planned items, the planning process can only suggest new daily rates that fall inside the acceptable rate increase and acceptable rate decrease boundaries defined for the item. A value of Cumulative manufacturing lead time means Master Scheduling/MRP calculates the planning time fence for the item as the plan date (or the next workday if the plan is generated on a non workday) plus the cumulative manufacturing lead time for the item. A value of Cumulative total lead time means Master Scheduling/MRP calculates the planning time fence for the item as the plan date (or the next workday if the plan is generated on a non workday) plus the total manufacturing lead time for the item. A value of Total lead time means Master Scheduling/MRP calculates the planning time fence for the item as the plan date (or the next workday if the plan is generated on a non workday) plus the total lead time for the item. A value of User-defined time fence means Master Scheduling/MRP calculates the planning time fence for the item as the plan date (or the next workday if the plan is generated on a non workday) plus the value you enter for Planning Time Fence Days for the item.

Planning Time Fence Days

An item attribute Master Scheduling/MRP uses when you set the Planning Time fence attribute to User-defined time fence. Master Scheduling/MRP calculates the planning time fence for the item as the plan date (or the next workday if the plan is generated on a non workday) plus the value you enter here.

postprocessing lead time

The time required to receive a purchased item into inventory from the initial supplier receipt, such as the time required to deliver an order from the receiving dock to its final destination.

preprocessing lead time

The time required to place a purchase order or create a discrete job or repetitive schedule that you must add to purchasing or manufacturing lead time to determine total lead time. If you define this time for a repetitive item, the planning process ignores it.

primary line

See lead time line

processing lead time

The time required to procure or manufacture an item. For manufactured assemblies, processing lead time equals the manufacturing lead time.

A finished item that you sell. See also finished good.

production line

The physical location where you manufacture a repetitive assembly, usually associated with a routing. You can build many different assemblies on the same line at the same time. Also known as assembly line.

production relief

The process of relieving the master production schedule when a discrete job is created. This decrements the build schedule to represent an actual statement of supply.

projected available balance

Quantity on hand projected into the future if scheduled receipts are rescheduled or cancelled, and new planned orders are created as per recommendations made by the planning process. Calculated by the planning process as current and planned supply (nettable quantity on hand + scheduled receipts + planned orders) minus demand (gross requirements). Note that gross requirements for projected available includes derived demand from planned orders. Note also that the planning process uses suggested due dates rather than current due dates to pass down demand to lower level items. See current projected on hand.

projected on hand

The total quantity on hand plus the total scheduled receipts plus the total planned orders.

purchase order

A type of purchase order you issue when you request delivery of goods or services for specific dates and locations. You can order multiple items for each planned or standard purchase order. Each purchase order line can have multiple shipments and you can distribute each shipment across multiple accounts. See standard purchase order and planned purchase order

purchase requisition

An internal request for goods or services. A requisition can originate from an employee or from another process, such as inventory or manufacturing. Each requisition can include many lines, generally with a distinct item on each requisition line. Each requisition line includes at least a description of the item, the unit of measure, the quantity needed, the price per item, and the Accounting Flexfield you are charging for the item. See also internal sales order.

Q

R

rate-based capacity

Capacity planning at the production line level. Required capacity, available capacity, and capacity utilization are calculated for individual production lines. Required and available capacity are stated in terms of production rate per line per week.

read consistency

A consistent view of all table data committed by transactions and all changes made by the user, up to the time of the read.

repetitive MRP plan

A set of optimal repetitive schedules which satisfy a given master schedule for repetitive items.

repetitive planning

The planning of demand or production for an item in terms of daily rates rather than discrete quantities.

Repetitive Planning (item attribute)

An item attribute the planning process uses to decide whether to plan material requirements for the item in terms of discrete quantities or repetitive daily rates.

repetitive planning period

A period, defined as a number of days, that smooths the production rate over time. With repetitive planning periods, you can prevent your planned repetitive production rate from fluctuating too frequently.

repetitive processing days

The number of days you plan to work on a repetitive schedule, from the first unit start date to the last unit start date.

repetitive rate

The daily rate for a repetitive schedule. See daily rate

repetitive schedule

A production order for the manufacture of an assembly on a continuous basis as defined by a daily rate, using specific materials and resources, over a period of time. A repetitive schedule collects the costs of production, but you report those costs by period rather than by schedule. Also known as flow order or scheduled rate.

repetitive schedule allocation

The process of dividing suggested aggregate repetitive schedules and allocating them across individual production lines, based on predefined line priorities and line speeds.

required capacity

The amount of capacity required for a resource or production line.

required hours

The number of resource hours required per resource unit to build one unit of the bill of resources item.

required rate

The production rate allocated to an individual production line by the repetitive schedule allocation process.

requisition

See purchase requisition and internal sales order

rescheduling assumption

A fundamental piece of planning process logic that assumes that existing open orders can be rescheduled into closer time periods far more easily than new orders can be released and received. As a result, the planning process does not create planed order receipts until all scheduled receipts have been applied to cover gross requirements.

reservation

A guaranteed allotment of product to a specific sales order. A hold is placed on specific terms that assures that a certain quantity of an item is available on a certain date when transacted against a particular charge entity. Once reserved, the product cannot be allocated to another sales order or transferred in Inventory. Oracle Order Entry checks ATR (Available to Reserve) to verify an attempted reservation. Also known as hard reservation.

resource

Anything of value, except material and cash, required to manufacture, cost, and schedule products. Resources include people, tools, machines, labor purchased from a supplier, and physical space.

resource group

Resources grouped together according to user-defined criteria to facilitate bill of resource generation and capacity planning.

resource offset percent

An operation resource field that represents, as a percent of the processing lead time for an item, the item when a resource is required on a routing. For example, if the processing lead time for an item is 10 days, and the resource is required on the fourth day, then the resource offset percent is 30%. Capacity uses resource offset percent to calculate setback days during the bill of resource load process.

resource roll up

Rolls up all required resources for a end assembly based on the routing and bill of material structure.

resource set

A grouping of bills of resources.

resource hours

The number of hours required by a repetitive schedule, discrete job or planned order.

rough cut capacity planning

The process of converting the master schedule into capacity needs for key resources. See routing-based capacity and rate-based capacity

rough cut planner

The routine that automatically calculates required resources for rough cut capacity planning (done when running a report or inquiry).

Rounding Control

An item attribute the planning process uses to decide whether to use decimal or whole number values when calculating planned order quantities or repetitive rates for the item. A value of Do not round order quantities the planning process uses and displays decimal values when calculating planned order quantities and suggested repetitive rates for the item. A value of Round order quantities means the planning process rounds decimal values up to the next whole number when calculating planned order quantities and suggested daily rates for the item. Planned order quantities and suggested daily rates are always rounded up, never down. The planning process carries any excess quantities and rates forward into subsequent periods as additional supply.

routing-based capacity

Capacity planning at the resource level. Required capacity, available capacity, and capacity utilization are calculated for individual resources assigned to operations on routings. Required and available capacity are stated in terms of hours per resource per week.

S

safety stock

Quantity of stock planned to have in inventory to protect against fluctuations in demand and/or supply.

Safety Stock (item attribute)

An item attribute the planning process uses to decide whether to use fixed or dynamically calculated safety stock quantities when planning material requirements for the item. A value of MRP-planned percent means the planning process plans to safety stock quantities it calculates dynamically as a user-defined percentage of the average gross requirements for a user-defined number of days. The user-defined percentage is defined by the value you enter for the Safety Stock Percent attribute for the item. For discretely planned items, the user-defined number of days is defined by the value you enter for the Safety Stock Bucket Days attribute for the item. For repetitively planned items, the planning process uses the repetitive planning period rather than Safety Stock Bucket Days. These safety stock quantities are dynamic in that they vary as a function of the average gross requirements calculated by the planning process for the item. A value of Non-MRP planned means the planning process plans to safety stock quantities calculated and maintained in Inventory. These safety stock quantities are fixed in that the Snapshot loads them from Inventory before the planning process and they do not vary unless they are recalculated in Inventory.

Safety Stock Bucket Days

An item attribute the planning process uses when you set the Safety Stock attribute for the item to MRP-planned percent. The planning process dynamically calculates safety stock quantities for the item by multiplying the average gross requirements for the item, over the time period defined by the value you enter for Safety Stock Bucket Days, by the value you enter for Safety Stock Percent.

Safety Stock Percent

An item attribute the planning process uses when you set the Safety Stock attribute for the item to MRP-planned percent. The planning process dynamically calculates safety stock quantities for the item by multiplying the average gross requirements for the item, over the time period defined by the value you enter for Safety Stock Bucket Days, by the value you enter for Safety Stock Percent.

safety stock quantity

The quantity suggested by MRP as additional supply needed for safety stock. This quantity can change according to an effective date set in Inventory.

schedule date

The date for a master schedule entry for an item. A schedule for an item has a schedule date and an associated quantity. For Order Entry, it is considered the date the order line should be ready to ship, the date communicated from Order Entry to Inventory as the required date any time you reserve or place demand for an order line.

schedule end date

For repetitive items, defines the end of the repetitive rate for a master schedule.

schedule entry

A schedule for an inventory item. For discrete items, stated by a date and quantity. For repetitive items, stated by a date, schedule end date, and quantity.

schedule smoothing

The manual process of entering quantities and dates on the master production schedule that represent a level production policy.

scheduled receipt

A discrete job, repetitive schedule, non-standard job, purchase requisition, or purchase order. It is treated as part of available supply during the netting process. Schedule receipt dates and/or quantities are not altered automatically by the MRP system.

set transaction read-only

An ORACLE RDBMS command that allows you to consider all the transactions committed after its execution. No transactions are written after the command is executed. See read consistency

setback days

The number of days set back from the assembly due date that a resource is required to build the assembly.

shift

A scheduled period of work for a department within an organization.

ship-to address

A location where items are to be shipped.

shipment relief

The process of relieving the master demand schedule when a sales order ships. This decrements the demand schedule to represent an actual statement of demand.

Shrinkage Rate

An item attribute the planning process uses to inflate the demand for the item to compensate for expected material loss. Enter a factor that represents the average amount of material you expect to lose during your manufacturing process. For example, if an average 20% of all units of the item fail final inspection, enter a shrinkage rate for the item of 0.2. In this example, the planning process always inflates net requirements for the item by a factor of 1.25 (1 / 1 - shrinkage rate).

simulation schedule

Unofficial schedules for personal use that contain the most current scheduled item information. You can print Simulation schedules, but you cannot confirm or send them via EDI.

simulation set

A group of capacity modifications for resource shifts to simulate, plan, or schedule capacity.

snapshot

The only phase under the memory-based planning engine. The snapshot takes a snapshot or picture of supply and demand information at a particular point in time. The snapshot gathers all the information about current supply and demand that is required by the planner to calculate net material requirements, including on-hand inventory quantities and scheduled receipts. Under the memory-based planning engine, explosion and planning occur in the snapshot phase.

snapshot delete worker

An independent concurrent process launched by the snapshot monitor that deletes planning data from the previous planning run.

snapshot monitor

A process, launched by the memory-based snapshot, that coordinates all the processes related to the memory-based planning engine.

snapshot task

A task performed by the snapshot or a snapshot worker during the planning process.

snapshot worker

A group of independent concurrent processes controlled by the snapshot monitor that brings information into flat files. This information comes from Work in Process, Bill of Materials, on-hand quantities, purchase orders, firm planned orders, routings, and Work in Process job resource requirements.

soft reservation

The planning process considers sales order demand soft reservation.

source forecast

When loading a forecast into another forecast, the source forecast is the forecast you load from.

standard planning engine

A planning engine that drives the planning process. This planning engine consists of three phases, each of which follows a strict sequence: the exploder, the snapshot, and the planner. These phases are followed by two optional phases: CRP planner, and maintain repetitive planning periods. See memory-based planning engine, planning process

standard purchase order

A type of purchase order you issue when you order delivery of goods or services for specific dates and locations for your company. Each standard purchase order line can have multiple shipments and you can distribute the quantity of each shipment across multiple accounts. See purchase order

statistical forecasting

A mathematical analysis of past transaction history, last forecast quantities, and/or information specified by the user to determine expected demand.

suggested aggregate repetitive schedule

The optimal repetitive schedule suggested by MRP to satisfy a given master schedule. The optimal schedule represents aggregated production for all lines and considers the constraints of planning periods, item lead time, firm schedules, time fence control, acceptable rate changes and overrun amounts.

suggested repetitive schedule

The schedule for an individual production line for a specific item that is derived from the Suggested aggregate schedule. MRP divides the suggested aggregate schedule for a specific line and item based on the production line attributes: priority, minimum and maximum rates.

T

time bucket

A unit of time used for defining and consuming forecasts. A bucket can be one day, one week, or one period.

time fence

A policy or guideline established to note where various restrictions or changes in operating procedures take place. The planning process cannot create or reschedule orders within the planning time fence. This gives the planner the ability to stabilize the plan and thereby minimizing the nervousness of the system.

time phased requirements

Requirements for resources where the need dates are offset by the lead time for those resources.

two-level master scheduling

A technique that facilitates the forecast explosion of product groupings into related master production schedules. The top-level MPS is usually defined for a product line, family or end product while the second-level is defined for key options and components.

U

underload

A condition where required capacity for a resource or production is less than available capacity.

utilization

Required capacity divided by available capacity.

V

W

work order date

The date to begin processing the paperwork for the discrete job. This date is offset from the start date by the preprocessing lead time.

worker
