Background: Planning Period Codes Maintenance

Use the Planning Period Codes Maintenance (MDM) program to add or change, copy and delete codes that set the length of periods that planning programs use to display supply and demand. See Road Map for work flow.

Planning Period Codes

You can define 48 periods, each from 1 to 999 days long. Your shop calender needs to be set up for the duration of the periods that you want to display. So if you set up a period code for months, to display them your shop calendar needs to extend 48 months into the future.

System-Provided Codes

These codes are provided; they can be modified as desired:

  • DFAULT
    The system uses DFAULT for planning displays and reports if you leave the item's Planning period field blank in Branch Item Maintenance (IMB) program. By default, the DFAULT code is set up with 48 5-day planning periods (similar to work week).

  • ATP
    The ATP code is used when the Order Processing availability system option (maintained in System Options Maintenance (XM) - Order Processing Options) is active. By default, the ATP period code is set up with 30 daily periods, then 10 periods of 5 days, followed by 8 21-day periods.

The system also provides these period codes that cannot be modified:

  • CALPER
    Rolling 12-month calendar periods

  • FYPER
    Rolling 12-month fiscal periods

  • MONDAY
    Weekly periods that begin every Monday

How Used

The Planning Profile Inquiry (MRD) and Planning Profile Maintenance (MPM) programs use the code selected in the item's record in the Branch Item Maintenance (IMB) program. If you do not select a code, the system uses the DFAULT code.

The Finished Goods Planning (MFP) and Material Requirements Planning (MRP) programs allow you to override the code selected for individual items. Select a code for the Select planning display period code program option in the Finished Goods Planning (MFP) and Material Requirements Planning (MRP) programs to use the same planning periods for all items. If you do not select a code for the program option, these programs use the item's codes selected in the Branch Item Maintenance program or the DFAULT code, if the item does not have a code.

In the Vendor Contract Maintenance (VCM), you enter a number for the Fab periods firm and Matl periods firm fields when you enter a long-term contract for supply. The code you selected for the item in the Branch Item Maintenance (IMB) determines the length of these periods.
