19 Work with Master Schedules

This chapter contains these topics:

19.1 Working with Master Schedules

DRP/MPS output consists of information in the time series and action messages. Use the time series information to decide whether to accept the planning that is suggested by the system or to override it. You should review the action messages for individual item numbers to determine which action, if any, to take.

Working with the master schedule consists of the following tasks:

  • Reviewing DRP/MPS Time Series

  • Reviewing Planning Families

  • Working with Messages

  • Adding a Freeze Code to a Purchase Order

  • Adding a Freeze Code to a Work Order

19.2 Reviewing DRP/MPS Time Series

Navigation

From Material Planning Operations (G34), choose DRP

From DRP Daily Operations (G3411), choose DRP Time Series/ATP Inquiry

Alternatively, to review information for Master Production Schedule, choose Daily MPS from the Material Planning Operations menu. Then, choose MPS Time Series from the MPS Daily Operations menu.

Use the DRP or MPS time series inquiry programs to review the master schedule. This is a record of time-phased supply and demand netting for selected items. This data is derived from the most recent generation or net change run. Use processing options in the DRP/MPS generation program to set up daily, weekly, or monthly time periods (buckets).

When you review a time series, you can:

  • Review the following information for an item:

    • MPS adjusted and unadjusted quantities

    • Time-phased inventory activity in any unit of measure

    • Available to promise quantities in any valid unit of measure

  • Identify the following information:

    • Time fences and item level leadtime

    • Cumulative leadtime occurrences

    • Manufacturing leadtime occurrences

  • Choose rows of information to select, suppress, or both

  • Toggle between two different quantity type displays that you specify in user defined code quantity lists

  • Run an online single item DRP or MPS generation

  • Summarize the following:

    • All demand lines into one DEM line

    • All supply lines into one SUP line

  • Choose the following:

    • Supply/Demand Inquiry, to view all actions that affect the item's quantities

    • Pegging Inquiry, to determine from where higher level demands are being generated

    • Message File Revisions, to review message detail and take any appropriate actions

    • Manufacturing Data Revisions, to verify item setup details

    • Detail Forecast Revisions, to review item forecasts and sales history

    • Rate Schedule Revisions, to review item rate schedules

To review the time series, complete one of the following tasks:

  • Review DRP time series

  • Review MPS time series

19.2.1 Quantity Types for DRP and MPS

Use the DRP or MPS Time Series Inquiry form to review the quantity types that the system has generated for the master schedule.

When you access DRP or MPS Time Series/ATP Inquiry, you can display different quantity types for the master schedule by creating a new user defined code table and changing the processing option to display this new table. You can also display two different tables, such as adjusted and unadjusted quantities, by changing the processing options.

Each table displays only those items that are pertinent to its application. For example, table 34/DR displays only those data items applicable to DRP items. If the code is not defined in table 34/DR, it will not appear on the DRP Time Series/ATP Inquiry form or report. DRP and MPS calculations are not affected by the appearance of this code.

If you do not specify a particular user defined code list, all quantity types display. However, the time series calculation is not affected by the quantity types that are not pertinent to the application.

Valid Quantity Types for DRP

The following lists the valid quantity types and descriptions that are defined for DRP in user defined code table 34/DR:

Quantity Types Description
+BA + Beginning Available
+IR + In Receipt Routing
+PO + Purchase Orders
-LEXP - Lot Expired
-FC - MPS/Forecast
-SHIP - Shipped Quantity
-SO - Sales Orders
-ID - Interplant Demand
=EA = Ending Available
+DRP + Distribution Requirements Plan
ATP Available to Promise
CATP Cumulative Available to Promise

Valid Quantity Types for MPS

The following lists the valid quantity types and descriptions that are defined for MPS in user defined code table 34/MS:

Quantity Types Description
+BAU + Beginning Available (Unadjusted)
+BA + Beginning Available
+IR + In Receipt Routing
+POU + Purchase Orders (Unadjusted)
+PO + Purchase Orders
+WOU + Work Orders (Unadjusted)
+WO + Work Orders
+RSU + Rate Schedule (Unadjusted)
+RS + Rate Schedule
-LEXP - Lot Expired
-FCU - MPS/Forecast (Unadjusted)
-FC - MPS/Forecast
-SHIP - Shipped Quantity
-SOU - Sales Orders (Unadjusted)

19.2.2 What You Should Know About

Topic Description
Period quantities Period quantities are either:
  • Adjusted - Assumes that the user will process the messages.

  • Unadjusted - Assumes that the action messages will not be processed. The U at the end of quantity types indicates that period quantities are unadjusted.

Time series calculation When you use a planning time fence rule that calculates the ending available that is based on the greater of forecast or customer demand, such as G, C, or H, the forecast is consumed. This means that the forecast is reduced by the amount of the customer demand in that same period.
ATP unadjusted calculation (ATPU) Unadjusted ATP assumes that no action messages have been processed.
Negative ATP/ATPU After you run the MPS generation, ATP/ATPU that have a negative value appear blank on the Time Series/ATP Inquiry form, except for the first period.
Cumulative available to promise unadjusted (CATPU) calculation The following calculation assumes the user has not acted on the messages:
  • CATPU = running total of ATPU

If ATPU is negative inside the planning time fence, then the system displays the resulting CATPU, whether it is positive or negative, in all previous time periods.

Suppressing blank lines You can use a function key to suppress the quantity types that have no data in them.

19.3 Reviewing Planning Families

Navigation

From Material Planning Operations (G34), choose DRP

From DRP Daily Operations (G3411), choose DRP Planning Family Review

After you generate DRP/MPS, you can review all item numbers that have messages. You can display the list of items that have messages using the following filters:

  • Branch/Plant

  • Thru Date

  • Planning Code

  • Message Type

  • Stocking Type

  • Planner Number

  • Buyer Number

  • Master Planning Family

Processing a message through P3401 is similar to P3411 but has some additional functionality. Since you are able to inquire on more that one item at a time in Planning Family Review, the program allows you to create orders for more than one item at a time, provided they have the same supplier. To consolidate by supplier turn on processing option #1 of the version of the Detail Message Review program that is called from the P3401.

An item can be inquired on by using planner number, buyer number, supplier number, or master planning family. Once there are a number of items on the screen that are to be processed on the same PO, place a 1 in the option field to exit to the detail message review program. Then to process the message follow the same procedure that was explained in the detailed message review section. Once the message has been cleared from the screen an F3 will exit back to the Planning Family Review program. To put an additional item on the order place a 1 in the option field of the next item that is to be processed. Once all of the items that are to be on the order are processed an F3 from the P3401 Planning Family Review program will bring up the PO Generator Window P43032. An F6 will then create the order for all of the messages that have been processed.

To review planning families

19.3.1 Processing Options

See Section 54.9, "Review Planning Family (P3401)."

19.4 Working with Messages

As an alternative to processing messages using Planning Family Review, you can access the messages directly using the Detail Message Review program.

Working with messages consists of the following tasks:

  • Reviewing detail messages

  • Processing work order messages

  • Processing purchase order messages

Work order messages on Detail Message Review have an order type of WO. Purchase order messages on Detail Message Review have an order type of OP.

The action messages for DRP/MPS/MRP are defined in user defined code list 34/MT. The character codes are hard-coded. Do not change the character codes in this list.

Caution:

Depending on the organization of your company, the person working with the DRP/MPS/MRP action messages should coordinate with Shop Floor or Purchasing personnel before taking action on messages affecting these departments.

19.4.1 What You Should Know About

Topic Description
Placing messages on hold You can place a message on hold so that the system does not change the message during the next generation (for example, to preserve a manual reminder). Because the system does not indicate that a message is on hold, JD Edwards World recommends that you add a planner remark that indicates the message is on hold.
Clearing messages You can remove a message from Detail Message Review if you do not choose to process it. To view the message again after it has been removed, enter a Y in the Cleared field.
Deleting messages You can delete any message that you have reviewed but did not process.
Selecting All Action Messages You can select all action messages for processing by choosing Select All Displayed Action Messages (F9). By doing so, the program enters a 2 by each line on the screen.

19.4.3 Processing Work Order Messages

Navigation

From Material Planning Operations (G34), choose Daily DRP

From Daily DRP Operations (G3411), choose DRP Detail Message Review

After you review the messages, you can process them. When you process a message, the system creates work order headers in the Work Order Master table (F4801) and assigns work order numbers. The system does not attach a parts list or routing at this time.

After you process the work order messages, the master schedule is firm through the date that the orders are processed. These firm orders are not automatically replanned in subsequent MPS generations.

To process a message in the P3411 the action code can remain I and you can place a 2 in the option column. If there are no errors, the system will clear the message from the screen. There are two common errors you might encounter:

  • You have not determined a supplier for purchased items, which you need to assign in the fold of the message.

  • There may a problem with the dates. Make sure that you have dates that are valid.

Once the system processes the message and it clears it from the screen. To create the order, press F3 and the PO Generator Window program (P43032) displays. Enter 9 in the Option field, the system cancels the processed message and the message displays on P3411 as unprocessed. Entering 1 in the Option field, in the window provides further detail to the items that in the order and their costs. To generate the order, press F6 and the order number displays next to the order type in the window. Once the system assigns an order number, that order exists in the F4311 file and you can locate it with the open orders program or Enter/Change Purchase Orders (P4311).

    Based on the message type, the system processes the work order as follows:

    • Released

    • Canceled

    • Deferred

    • Expedited

    • Increased

19.4.3.1 What You Should Know About

Topic Description
Processing messages When you process a message, the system removes it from the Detail Message Review form. To view the message again, enter a Y in the Cleared field and scroll to the end of the message list.
Fixed order quantity (FOQ) When you use FOQ, MPS/DRP does not generate an Increase message for an existing order to cover demand. Instead, the system generates Order messages in multiples of FOQ as needed to cover the demand.
Order status When you create or update an order, you can modify the status to indicate the stage of production. To do so, enter a new status in the Status field in the fold area. The system displays this field only for those messages that are related to order processing.
Past Dates You can process an order message with past dates, with no error/warning, by changing the dates to the system date.

19.4.4 Processing Purchase Order Messages

Navigation

From Material Planning Operations (G34), choose Daily DRP

From Daily DRP Operations (G3411), choose DRP Detail Message Review

You can process a purchase order message using one of following methods:

  • Process a single action message without blanket order checking or consolidation

  • Process one or more action messages with blanket order checking

  • Process messages using purchase order consolidation to place more than one item on a purchase order

  • Process purchase order messages using a planning family

  • Process messages using the Supplier Scheduling system

JD Edwards World recommends that you set up different versions of the previous methods to expedite processing messages. That is, set up one version to process a single action message without blanket order checking or consolidation, another version to process one or more action messages with blanket order checking, and so on.

Complete the following tasks:

Process a single action message

Process messages using consolidation

Cancel items on a purchase order

Depending on how you set the processing option for the DRP/MPS generation program, the program creates either a purchase requisition (OR) or a purchase order (OP). The program places a user ID on the purchase order and uses the system date as the date that the purchase order was created.

In addition, the program creates the purchase order in the purchasing unit of measure, even though the action message displays the primary unit of measure. The program makes the proper unit of measure conversions. After the next DRP/MPS regeneration, the quantities associated with processed messages appear in the time series display on the +PO quantity type row.

Processing messages will firm that portion of the DRP/MPS replenishment plan. Subsequent DRP/MPS regeneration will not change the timing or quantities associated with previously processed messages. However, if the new regeneration finds a mismatch between the supply and demand quantities or dates, the program issues a message recommending realignment of the existing +POs.

19.4.4.1 What You Should Know About

Topic Description
Processing messages using blanket order checking A processing option controls whether the system verifies the existence of a blanket order for the item you are processing. If the part has any open blanket orders, the system displays the Blanket Order Release form in the Purchasing system. The system releases the amount that you are processing against the blanket order.
Consolidating multiple item numbers You can consolidate several order lines for the same supplier into one purchase order. Do this by setting a processing option for DRP Detail Message Review.
Process messages using a planning family You can process messages by family using DRP Planning Family Review. After you select all the items that you want to process, DRP Detail Message Review appears for each item that you selected. Process the messages for each item in the same way you process messages using consolidation.
Freezing purchase orders When you sign a purchasing contract with a supplier, you can freeze purchase orders in time and quantity so that DRP/MPS does not generate any action messages to change orders.
Obsolete or use-up items When processing planning messages, JD Edwards World respects O or U stocking type designations for items by not allowing automatic creation of a purchase order from planning message processing.
