SAP MM: MRP Carrying out the Forecast with Reference to Another Material

If no historical data exists for materials, which the system can access during the forecast, it is possible to use another material for the forecast. To do this, you must define a so-called reference material for consumption as well as a reference plant, a validity date, and a multiplier.

If you have defined a reference material, the system accesses the historical data of the reference material during the forecast up to the specified validity date. From the validity date, the system then uses the material’s own historical data.

By entering a multiplier, you can define that only a certain percentage of the consumption quantity of the reference material is used for the forecast.
