Forecast Consumption Across Multiple Periods

Forecast consumption is associated with planning fence rule H.

Forecast consumption periods (FCPs) are user defined and stored in the Forecast Consumption Periods table (F3405). Within an FCP, the system processes sales orders against the gross (unadjusted) forecast (quantity type of -FCSU) on a first-in, first-out (FIFO) basis. The system creates additional time periods if the forecast end dates of the consumption period do not coincide with the period end dates of the time series.

The additional forecast consumption time periods are incremental to the number of time periods that are identified in the MRP/MPS Requirements Planning program (R3482). The total for all time periods cannot exceed 52.

The system only applies the forecast consumption calculations if you set the appropriate processing option for the Master Schedule Planning - Multiple Plant program (R3483). To use forecast consumption, an item's planning fence rule must be H, and the planning fence must be 999. These values are set on the Additional System Information form in the Item Master (P4101) or Item Branch (P41026) programs.
