This chapter covers the following topics:
Line scheduling is the process of sequencing and scheduling work to be done on your balanced flow lines. You create flow schedules to represent the volume and mix of products to be produced. The objective of line scheduling is to synchronize production as tightly as possible to customer demand, as well as establishing an achievable pace and consistent flow of products throughout the production process and supply chain.
The Line Scheduling Workbench is used by schedulers to create and manage flow schedules. You can simulate the assignment of work to production lines, and schedule work on specific lines. While you can view all scheduled orders (such as discrete jobs, repetitive schedules, and flow schedules) through the workbench windows, the only type of work you can create and schedule in the workbench is a flow schedule. The following illustration shows the process flow for line scheduling.
The Line Scheduling Workbench Options window is the interface to the other planning windows in line scheduling. The functions available through the workbench are:
Viewing Unscheduled Orders
You can view unscheduled orders in the Line Scheduling Workbench Unscheduled Orders window. You have the option to display the unscheduled planned orders or sales orders. These unscheduled orders can be converted into flow schedules.
Creating and Maintaining Flow Schedules
You can create and modify schedule quantities and dates of flow schedules.
Prioritizing and Sequencing Flow Schedules
You can schedule your flow schedules either by using the scheduling rules provided, or ones that you have defined.
Flow Schedule Completion
You can perform completion transactions for scheduled flow schedules when production is finished.
Mixed Model Map
The Mixed Model Map is used to monitor your line design by balancing a line against a specified statement of demand.
Roll Flow Schedules
You can roll flow schedules forward, based on under completions and overcompletions, in order to adjust future production.
Deleting Flow Schedules
You can delete flow schedules in order to provide a clean slate for new schedule generation.
Checking the Availability of Components
You can access the ATP Results window to view component availability.
Viewing Resource Load in Relationship to Available Capacity
You can view a graphical representation of the required load of the line and its associated resources.
A scheduling rule determines the logic used to set the timing of the flow schedules. The rule is comprised of an algorithm and the criteria used in sequencing the flow schedules. Oracle Flow Manufacturing provides several types of scheduling rule options. Pre-defined scheduling rules combine a system algorithm with sequencing criteria. In addition, there are two methods to create your own rules.
Pre-defined scheduling rules combine a system algorithm and one sequencing criteria. Five pre-defined rules are provided.
System-Defined Rules
User-defined scheduling rules allow you to combine a system algorithm with one or more of the system provided criteria.
User-Defined
You can also create your own rules defined by modifying the custom line scheduling procedure that is executed at the time of scheduling flow lines.
Three algorithms are provided for line scheduling:
Flow schedules are sequenced according to criteria, and the demand is placed in the days of the scheduling horizon. Starting with the first available day, demand is scheduled until capacity is reached.
Criteria Order is used to determine the sequence of the flow schedules. Beginning with the demand with lowest sequence (or highest priority), demand scheduled in ascending order.
Flow schedules on each day are sequenced based on the demand ratio. In this algorithm the production rate for each item is calculated for each day. Therefore, items with higher demand have a higher production rate. That rate is then used on each day of the scheduling horizon.
Production rate for an item on a particular day is determined by multiplying the available capacity on that day by the demand ratio for the item.
In this algorithm the production rate for different items is calculated in order to establish a production rule pattern for a mix of items. The rule pattern is repeated within a day and across the scheduling horizon.
You can sequence flow schedules using one or more of the following values:
Order Entry Date
Order Priority
Order Promise Date
Order Request Date
Order Schedule Date
Production Sequence Forward
Production Sequence Reverse
The criteria is listed in the order of priority. For example, you can sequence by Order Request Date and Order Entry Date. The Order Request Date has priority 1, the Order Entry Date has priority 2. If two different flow schedules have the same order request date, then the order with the earliest order entry date is scheduled first.
Criteria are only applied to unscheduled sales orders. For unscheduled planned orders, the generated Planned Order Due Date value is the only criteria used for sequencing.

Define Scheduling Rules Window
You can view scheduling rules and sequencing criteria, as well as define your own custom rules in this window.
To view existing scheduling rules
Navigate to the Define Scheduling Rules window.
From the Query menu choose Enter, and then choose Run.
Use the Arrow keys to page through the list of scheduling rules.
To define system-defined or user-defined scheduling rules
Navigate to the Define Scheduling Rules window.
Enter the name of the scheduling rule in the Name field.
If you are creating a custom rule, this value is user-defined. The following rules are provided in the system:
Mixed Model - mixed model by order request date
Level Daily Rate- level daily rate by order request date
Request Date- order request date with no leveling
Schedule Date - order schedule date with no leveling
Promise Date - order promise date with no leveling
Production Sequence Forward - order schedule date, order production date sequence in ascending order with no level loading
Production Sequence Reverse - order schedule date, order production date sequence in descending order with no level loading
Enter the description of the rule in the Description field.
For rules you create, it is beneficial to have the name and description reflect the algorithm being used.
Uncheck the Enabled check box if you are disabling an existing rule, otherwise leave it marked.
This is a Yes/No flag indicating whether this rule is currently in use.
Select the Default check box if this rule is to be your default scheduling rule.
This is Yes/No flag indicating if this is the default rule. The default rule is used unless it is overridden; there can only be one default rule for scheduling.
If this is a system-defined rule, choose the System Defined option button. Otherwise, if this rule is to be defined by a user procedure, proceed to Step 9.
This option button enables the region for rules using system provided algorithms and sequencing criteria.
Select an algorithm in the Leveling box.
The system algorithm values in this box are:
No Level Loading–sequencing is calculated only by priority criteria
Level Daily Rate–the calculation is the ratio of total demand for each item, multiplied by the line rate
Mixed Model–daily demand is calculated from different products and different lot sizes
In the Criteria Name box, select criteria values from the list of values.
Enter one or more values in order of priority. For example, if you select Order Request Date first, and then Order Entry Date–the order with the earliest request date and earliest order entry date is scheduled first.
Order Entry Date
Order Priority
Order Promise Date
Order Request Date
Order Schedule Date
Production Sequence Forward
Production Sequence Reverse
For user procedures, choose the User Defined option button.
This option button sets the rule to user-defined. To add custom line scheduling logic, modify the Custom_Schedule procedure (MRPPCLSS.pls/MRPPCLSB.pls).

The Line Scheduling Workbench Options window is the starting window from which to access line scheduling options. From this window you can access the other windows to view unscheduled orders, create flow schedules, view and modify existing schedules.
Honor Planning Recommendations and Primary Routing Only Check Boxes
The following list presents the combined behavior of these check boxes:
Honor Planning Recommendations checked/Primary Routing Only unchecked
Shows only planned orders that planning has recommended on the selected line.
Honor Planning Recommendations unchecked/Primary Routing Only checked
Shows only planned orders of assemblies that have primary routing on the selected line.
Honor Planning Recommendations unchecked/Primary Routing Only unchecked
By default shows planned orders of assemblies that have routing on the selected line.
Honor Planning Recommendations checked/Primary Routing Only checked
Shows all the planned orders which planning has recommended on the selected line if the assembly of the planned order has primary routing on the selected line.
To view unscheduled orders, create flow schedules, or modify existing schedules
Navigate to the Line Scheduling Workbench Options window by selecting an organization and production line.
The Line Scheduling Workbench Options window displays information on the selected line. You can access the other windows using the defaulted information, or you can enter other values.
The Daily Production Rate is information for this production line. It is the calculation of the Hourly Production Rate multiplied by the number of work hours for this line.
Optionally select a Schedule Group value.
The Schedule Group is defined in Work in Process. The value entered here is used as a default for any schedules created.
In the Unscheduled Orders region, select the Type and Order Date ranges for unscheduled orders.
You can select Sales Orders or Planned Orders. Sales orders are created from Order Management transactions; Planned Orders are created from all of your planning production.
If you select Planned Orders, then select Primary Routing Only check box to see planned orders for assemblies that have primary routing on the selected line.
Select Honor Planning Recommendations along with Primary Routing Only check box to filter planned orders based on planning recommendations. As planning can recommend lines that have assemblies with alternate routings, this helps you to filter those orders with demand type as Planned Orders.
Note: If you create multiple plans marked as production – the Production flag is checked on the Master Production Schedules window or the MRP Names window– you can create duplicate flow schedules.
Note: Flow schedules are created from planned orders in the Line Scheduling Workbench—not releases from the Planner Workbench.
The Order Dates range determines which orders are displayed on the Unscheduled Orders window, and signifies the period of time to consider demand for scheduling. It refers to either schedule ship date of sales orders, or due dates of planned orders.
In the Scheduling region select a scheduling rule.
Select beginning and ending date values.
Flow schedules are created for the date ranges that you select. See: How Scheduling is Calculated
Check the Flex Tolerances check box if you want to enable flexible tolerance fences in your scheduling calculations.
Flexible tolerance fences provide temporary increases to capacity to handle increases in orders. The line rate is adjusted by the tolerance fence percentage before scheduling rules are applied. Tolerance fences are set up when creating line definition. See: Defining Production Lines and Tolerance Fences, Oracle Work in Process User's Guide
Choose one of the following for line scheduling functions:
Unscheduled Orders: Displays the Unscheduled Orders window showing all demand that has not been converted into Flow schedules. See: Viewing Unscheduled Orders

This window displays fields for assembly number, order date, the unscheduled quantity, the quantity available to schedule, sales order number, and corresponding sales order lines.
Choose Link to link Flow schedules to sales order lines. See: Linking Sales Orders to Schedules
Choose Schedule to create schedules for records selected. The Flow Schedule Summary window displays to view schedule information of planned and completed quantities at an aggregate level. This method enables you to create Flow schedules according to filtering criteria, schedule rule, and line capacity.
Choose Implement to create schedules for all unscheduled orders selected. These orders are scheduled without regard to the line capacity or scheduling rules. See: How Scheduling is Calculated
Linking Sales Orders to Schedules
Flow schedules are created from sales order demand, planned order demand, or created manually. Manually created schedules or schedules that have had the demand type removed do not reference a sales order. The linking functionality enables you to establish a reference to sales orders during Flow schedule creation - if one does not already exist, or if it is linked to a planned order. This functionality is accessed from the Unscheduled Orders window.
Note: To consume the sales order demand, select the Consume Order check box. This will consume the sales order into flow schedules created from planned orders and these planned orders will not appear as unscheduled orders. But if you want to schedule it separately, then do not select the check box and the planned orders whose flow schedules are linked to the sales order appear as unscheduled orders.
By default the Consume Order check box is not displayed, as it is a folder field. To display the field, select the field from the folder. By default, the check box is unchecked
When you choose Link from the Unscheduled Orders window, sales order quantities are matched to selected schedule quantities that fall within the date range specified. A Note window displays the linking results:
Sales orders linked fully
The quantity in the sales order line matches total quantity in the Flow schedules.
Sales orders linked with excess quantity
The quantity in the sales order line is less than the total quantity in the Flow schedules.
Sales orders linked partially
The quantity in the sales order line is greater than the total quantity in the Flow schedules. Flow schedules fulfill partial quantity of the sales order line.
Sales orders failed to link
Sales order is not linked to any Flow schedule.
For example, you may have sales order and unscheduled order quantities as demonstrated in the following table. The linking process matches sales order demand with unscheduled demand resulting in some linked orders, and others not linked.
Unscheduled Sales Order Demand | Flow Schedule Quantities not Linked | Matched Quantities |
---|---|---|
Order1, 6 each | FS1, 2 each | Order1, FS1. 2 |
- | FS2, 2 each | Order1, FS2, 2 |
- | FS3, 3 each | Order1, FS3, 3 |
Order2, 4 each | FS4, 2 each | Order2, FS4, 2 |
- | FS5, 2 each | Order2, FS5, 2 |
Order3, 6 each | FS6, 2 each | Order3, FS6, 2 |
Order4, 8 each | - | Order4, 0 |
Order1, 6 each | FS1, 2 each | Order1, FS1. 2 |
In this example, the Note window displays these results:
1 sales order linked fully (Order2)
1 sales order inked with excess quantity (Order1)
1 sales order linked partially (Order3)
1 sales order failed to link (Order4)
You access both flow schedule summary and detail information from the Line Scheduling Workbench Options window. This allows you to view, create, and change flow schedules. The Flow Schedule Summary window shows schedule information grouped by assembly and date, showing the planned and completed quantities at an aggregate level. You can then navigate to the Flow Schedule Details window for more information on the assembly and its components.
Note: Oracle Project Manufacturing feature of model/unit effectivity is supported in the Line Scheduling Workbench. If this feature is enabled, the Unit Number field is visible when viewing unscheduled orders and passed on to new flow schedules created. See: Model/Unit Effectivity, Oracle Project Manufacturing Implementation Manual.

Scheduling rules determine the timing of the flow schedules using the following logic in the calculation routine:
Sequence is determined by the criteria in the rule.
Demand is sequenced using the criteria in the scheduling rule. The priority of each criteria determines the order in which it is applied.
The first flow schedule created goes to the first available date in the scheduling horizon.
Flow schedules are created for orders starting with the first available due date that has capacity. Flow schedules are not created for orders than cannot be scheduled within the scheduling horizon.
This process of attaining the line rate for each day continues until the end of the scheduling horizon.
Capacity is calculated for the day using the line rate, subtracting the existing workload (flow schedules, discrete jobs, repetitive schedules) for that day. When available capacity for the day is attained, schedules are slated for the next day until the end of the scheduling horizon.
If you are using flexible tolerance fences, scheduling begins after the last day indicated from the Days in Advance value.
Tolerance fences provide temporary increases to capacity above their normal operating rate to handle rises in orders.
Oracle Flow Manufacturing supports shifts that cross calendar days, as long as the start of the shift falls on a working day. To accomplish this, ensure that the Oracle Bills of Material Workday Calendar, the line definition, and the scheduling window you use in the Line Scheduling Workbench are synchronized. For example, you can specify the workday calendar is setup for the days Monday - Friday, and three shifts:
Shift 1—7 am to 3 pm
Shift 2—3 pm to 11 pm
Shift 3—11 pm to 7 am
The line definition is then set up to work from 7 am to 7 am. To schedule all shifts for Friday, ensure that the current schedule on the Line Scheduling Workbench is set to Saturday at 7 am. The Line Scheduling Workbench then schedules through 7 am, Saturday—even if Saturday is a non-work day.
You cannot start a shift on a non-work day. For example, if you have a shift starting at 11 pm on Sunday, the Line Scheduling Workbench cannot schedule for the first hour of the shift. See: Using the Workday Calendar, Oracle Bills of Material User's Guide
The scheduling rule is comprised of an algorithm and the criteria used in sequencing the flow schedules. Oracle Flow Manufacturing provides the following three algorithms:
No Level Loading
If you select a scheduling rule that has no level loading, the criteria defined in the scheduling rule is used to prioritize and sequence the orders. Orders are scheduled with capacity considerations beginning with the first available date of the scheduling date range. If the entire quantity of the sales order cannot be satisfied on a date, the remaining quantity is scheduled on subsequent days where capacity is available.
Level Daily Rate
If you choose to schedule for each day using the level daily rate, each item is scheduled at a rate in regard to the demand ratio of the item. The demand ratio of an item equals the total demand of the item divided by the grand total demand.
Mixed Model
This algorithm establishes a pattern to manufacture items in order to meet demand. The pattern distributes units according to the demand of each item for each day.
The following are functions available in the Tools Menu for maintaining flow schedules. This menu is available through any of the windows in the Line Scheduling Workbench.
Completions
Mixed Model Map
Preferences
Roll Flow Schedules
Delete Flow Schedules
You can complete flow schedules through the Work Order-less Completions window. Choose Completions from the Tools menu to display the window. The details of the schedules you selected are defaulted in the Work Order-less Completions window.

You can access the Mixed Model Workbench from the Tools menu. The Mixed Model Map Workbench helps you to create and monitor your line design by balancing a line against a specified forecast.
You can use the Mixed Model Map to compare line information with demand requirements. This provides information to adjust resources on the line to meet the demand. The output of the Mixed Model Map will give you the line rate.
The Preferences window is used to change the quantity types that show on the Flow Schedule Summary window.
The Planned quantity is originally calculated when the flow schedule is created using the rule and available capacity. The Completed quantity is updated when you perform a completion on this schedule. The Variance is the difference between Planned and Completed quantities.
You must maintain flow schedules so that production schedule information is accurate; and planning information such as Available-To-Promise and demand for components is current. The Roll Flow Schedules program is designed to allow you to adjust future schedules based on actual performance in the past. You adjust the quantity on future production schedules based on the completion quantities and past production. You can change schedules for a line, a range of lines, or for all lines at once.
Note: Planning calculations do not consider flow schedules with past due dates. Use the Roll Flow Schedules window to update your flow schedules in order to keep planning accurate.
Note: The Feeder Line Synchronization program ignores flow schedules created from the Roll Flow Schedules program. You must roll schedules on both the parent and feeder lines.
Three options are available for adjusting schedules: Close All Past Schedules, Roll With Details, and Spread Evenly Without Details.
Close All Past Schedules
This option closes all open past due schedules.
Note: Schedules are automatically closed when the completion quantity is greater than or equal to the planned quantity.
Closed flow schedules cannot be changed or rolled with details, and they are denoted with gray fields. You can close individual or a group of schedules. For example, a customer might reduce the order quantity because a delivery date can not be made. The original schedule is closed and the program does not roll the excess quantity no longer needed.
Roll With Details
This option rolls any open schedules within the specified date range to a single date. The new schedules maintain the original schedule details including the order information, build sequence, and alternate bill of material or routing information. The rolled schedules are scheduled at specific times if no schedules exist on the rolled to date.
Note: The original schedules are closed after the roll. Therefore the same schedule cannot be rolled multiple times, nor can you change the original schedule once it has been rolled. The schedule number from the original schedule is rolled to the new schedule.
Spread Evenly Without Details
You can spread schedules without order information evenly across multiple days, for use in a repetitive environment, allowing you to:
Calculate variance and roll by line and item
Consider both the planned quantity and the completed quantity when rolling overcompletions
Schedule specific times for the rolled schedules if no schedules exist on the specific rolled day
Note: When rolling flow schedules without details, if you roll the same flow schedules multiple times, it is possible to create excess supply.
To roll flow schedules forward
Select Roll Flow Schedules from the Tools menu.
The Roll Flow Schedules Parameters window appears.
Select an Option.
Your choices are:
Close All Past Due Schedules
Roll With Details
Spread Evenly Without Details
Select an Output option.
