Understanding Multifacility Forecast Consumption

Multifacility forecast consumption in MRP is a process to reduce the forecast quantity through the number of sales orders and shipped orders. The goal of forecast consumption is to have the forecast quantity be greater than the total of sales orders and shipped orders. The forecast quantity is consumed either fully or partially. For example, when the sales order quantity is greater than the forecast quantity, then the forecast quantity is fully consumed. The option that you select is dependent on the need to forecast interplant demand.

The system uses user-defined code (UDC) for quantity types (34/QT) for multifacility consumption:

Quantity Type	Description
-FIDU	Firm interplant (unadjusted). This quantity type represents orders for transfer sales that the system generates. This quantity does not use planning messages to increase, decrease, expedite, or defer the orders.
-FID	Firm interplant demand. This quantity type represents orders for transfer sales that the system generates. This quantity uses planning messages to increase, decrease, expedite, or defer the orders.
-TIU	Total independent demand (unadjusted). This quantity type represents the total quantity that the system uses to consume forecast when you use forecast consumption. When you compare customer demand to forecast quantity (for example, the G or the C planning rule), -TIU is the quantity that the system uses as customer demand. This quantity might or might not include interplant demand (-ID and -FID). Interplant demand depends on the Interplant Demand processing option for the Master Planning Schedule - Multiple Plant program (R3483).
-TI	Total independent demand. This quantity type represents the quantity for customer demand after the system runs forecast consumption logic.
-ID	Interplant demand. This quantity type represents the quantity of demand that the system generates to support another facility's requirements.
