Explanation
To meet the business requirements of forecasting by product material for each distribution partner, the administrator should add a custom Material dimension to the Forecast Fact and Forecast Set objects. This dimension can store the material attribute of each product and allow the users to filter and group the forecast data by material. The administrator should also clone and use the standard Data Processing Engine (DPE) definitions to populate the new custom metrics. The DPE definitions are the logic that transforms the source data into the forecast data. By cloning the standard definitions, the administrator can leverage the existing logic and modify it to include the custom Material dimension. The administrator does not need to configure a custom Forecast Context or create new DPE definitions from scratch.
