Defining Forecast Sets
Whether you forecast products at the Order Management business unit level, forecast items at the Inventory business unit level, or use planning BOMs to forecast at the Inventory business unit level, you must define one or more forecast sets. Use the Forecast Sets page to define different versions of the forecast for PeopleSoft Supply Planning to create what-if scenarios with different versions of the material and capacity plan based on the different forecasts.
You might, for example, have three versions of a forecast: a conservative forecast, a most likely forecast, and an optimistic forecast. For each case, you can define forecast quantities by item. You use forecast sets for product forecasts in order management and item forecasts in inventory.
If you use Demantra Demand Management forecast data, you do not have to define forecast sets, because you obtain the forecasts from PeopleSoft Publish Forecast tables that are available in the Advanced Planning component. Demantra Demand Management provides a flat file (forecast.txt) of forecasts through the Process Integration Pack. Using the PeopleSoft Import Forecast routine, you can import the file into the Publish Forecast tables in PeopleSoft. After the import, the file is available for use by other PeopleSoft modules such as PeopleSoft Supply Planning and Inventory. To access the routine, select
