Parameters

These processing options control processing criteria.

1. Generation Mode

Specify the generation mode. A gross regeneration includes every item in the data selection. A net change includes only those items in the data selection that have changed since the last time you ran the program. Values are:

1: Net change

2: Gross regeneration

2. Generation Type

Specify the generation type. See the help for the Parameters tab for detailed information. Values are:

1: Single-level MPS/DRP.

2: Planning bill.

3: Multilevel MPS.

4: MRP with or without MPS.

5: MRP with frozen MPS.

The generation type selection is important:

• Generation Type 1, single-level MPS/DRP.

  You can use this generation type either in a distribution environment for purchased parts with no parent-to-component relationship, or in a manufacturing environment with parent-to-component relationships. When you use this generation type, the system performs these actions:

  - Produces a time series for each item that you specify in the data selection with a planning code of 1 on the Plant Manufacturing Data tab of the Work with Item Branch form. This code indicates whether the item is manufactured or purchased.

  - Does not explode demand down to the components for manufactured items. Use generation type 1 if you first want to process only the master-scheduled end-items. Thus, you can stabilize the schedule before placing demand on the components.

  - Does not create pegging records.

• Generation Type 2, planning bill.

  Use this generation type to plan for items that have a planning bill of material. A planning bill has a pseudo parent item that is never actually manufactured; rather, it is used to represent the average composition of a group of products.

  This generation type explodes a parent forecast to its components by multiplying the parent's forecast by the feature planned percent (from the bill of material) for each component. The program then creates a new forecast for the components. For example, a pseudo parent item bike might have a forecast of 1,000. The program distributes that forecast into a forecast of 100 mountain bikes, 500 touring bikes, and 400 commuter bikes.

  To use this generation type, set up the following information correctly:

  - The pseudo parent item must have a planning code of 4 on the Additional System Information form: Plant Manufacturing tab.

  - The components must have a planning code of 5.

  - The feature planned percents must be set up correctly in the bill of material.

  - You must specify in the processing options the forecast type to read from the parent and to create for the components.

• Generation Type 3, multilevel MPS.

  This generation type is an alternative to generation type 1 and performs a complete top-to-bottom processing of master-scheduled items. For all parent items that you specify in the data selection, the program explodes demand down to the components. You must specify all of the items to be processed in the data selection, not just the parent items. The program also creates pegging records.

• Generation Type 4, MRP with or without MPS.

  This generation type performs the same functions as generation type 3. After you perform a complete generation and stabilize the master schedule, you can limit data selection to MRP items (with planning codes of 2 or 3), thereby reducing processing time. This action is possible because the system still stores demand from the master-scheduled items in the MPS/MRP/DRP Lower Level Requirements File table (F3412).

• Generation Type 5, MRP with frozen MPS.

  This generation type freezes the master schedule after it has been stabilized. Before using this generation type, make all necessary adjustments to master-scheduled items and release orders to provide supply for the demand. This generation type freezes the entire planning horizon, which is similar to the way the freeze fence freezes a part of the horizon. The results of running this generation type are:

  - No new orders will be planned.

  - No messages for existing orders will be created.

  - The adjusted ending available quantity can be negative.

  - Demand is exploded down to components from existing work orders only. No -PWO demand from parent items exists; only -FWO demand exists.

3. UDC Type

Specify the user-defined code (UDC) table (system 34) that contains the list of quantity types to be calculated and written to the F3413 table. The default value is QT.

4. Version of Supply/Demand Inclusion Rules

Specify which version of supply/demand inclusion rules the program reads. These rules define the criteria that are used to select items for processing.
