Performance

These processing options define output, and increase or decrease processing time.

1. Clear F3411/F3412/F3413 Tables

Caution: Use this processing option with extreme caution!

If you enter 1, the system purges records in the F3411, F3412, and MPS/MRP/DRP Summary File (F3413) tables.

Access to this program should be limited. If multiple users run this program concurrently with this processing option set to 1, a record lock error results and prevents complete processing. Values are:

Blank: Do not clear tables.

1: Clear tables.

2. Input B/P Where Planning Tables Will Be Cleared (input branch/plant where planning tables will be cleared)

Specify which branch/plant records in the F3411, F3412, and F3413 tables are purged.

Note:

This option is only valid when the Clear F3411/F3412/F3413 Tables processing option on the Performance tab is set to 1 and the Delete Branch/Plant processing option has a valid branch/plant.

This processing option enables a preprocess purge of these tables. If this processing option is not enabled or set to Blank, the system purges records for a given branch/plant and item as you plan the item. Depending on processing option combinations, these scenarios can occur:

Example 1:

Clear F3411/F3412/F3413 Tables is set to 1.

(a) Delete Branch/Plant is set to Blank.

All records from the three tables will be prepurged.

(b) Delete Branch/Plant contains a valid branch/plant number.

Records for all the items that belong to the valid branch/plant will be prepurged from the three tables.

No records will be prepurged from the three tables.

Example 2:

Clear F3411/F3412/F3413 Tables is set to Blank.

Delete Branch/Plant is not active.

No records from any of the three tables will be prepurged.

3. Initialize MPS/MRP Print Code.

Specify a value to initialize records in the F4102 table.

If you enter 1 in this processing option, the program initializes every record in the F4102 table by setting the Item Display Code (MRPD) to Blank.

If you leave this field blank, processing time is decreased. The system does not clear the records in the F4102 table.

Regardless of how you set this processing option for each item in the data selection, the MRPD field is updated as follows:

1 if messages were not created.
2 if messages were created.

The Print Master Production Schedule program (R3450) enables you to enter data selection based on the MRPD field. Values are:

Blank: Do not initialize.

1: Initialize.

4. Messages And Time Series For Phantom Items

Specify whether the program generates messages and time series for phantom items. Values are:

Blank: Do not generate.

1: Generate.

5. Ending Firm Order Status

Specify the work order status at which messages are no longer exploded to components. If you leave this processing option blank, all messages are exploded to components.

6. Extend Rate Based Adjustments

Specify whether adjustments for rate based items are exploded to components, thereby creating messages for the components. Values are:

Blank: Do not extend.

1: Extend.

7. Closed Rate Status

Enter the status of closed rates. When planning for a rate based item, the program does not consider rate orders at this status or higher.

8. Set Key Definition For Table F3411 and 9. Set Key Definition For Table F3412

Specify to run multiple MRP/MPS jobs concurrently. The value that you enter specifies the range for the number of records in the F3411 and F3412 tables for a given run. This value must be large enough to include the number of records that will be generated for the table. For example, if you enter a value of 8 for the first run and 10 for the second run, the range of records that the system reserves for two simultaneous MRP/MPS runs would be as follows:

First run:

The system reserves records in the range of [1] to [1 × 10^8], or 1 through 100,000,000.

Second run:

The system reserves records in the range of [1 × 10^8 + 1] to [2 × 10^10], or 100,000,001 through 20,000,000,000.

Note: The values that you enter are the exponents in the previous calculations. Enter a value from 7 to 14. If you do not enter a value, the system uses 10.

This processing option is applicable only when a subsequent MRP/MPS job is submitted while an existing job is currently running. The number of records that the MRP/MPS Requirements Planning program and Master Planning Schedule - Multiple Plant program (R3483) generate is based on the values that you enter in this processing option. You determine the optimum number of records that the system includes. All values should be the same for all versions. If version settings differ, the system might generate unpredictable results.

10. Suppress Time Series

Specify whether the MRP/MPS Requirements Planning program generates the time series. Values are:

Blank: Generate.

1: Do not generate.

Note: Performance improves if the system does not generate the time series.

11. Planning Control UDC Type

Specify the UDC table in system 34 that contains the list of planning control flags. The default value is PC.
