I am able to load forecast items and forecast dates using MRP_FORECAST_INTERFACE Table. MY requirement is to load the FORECAST DESIGNATORS also. How can i do this, Is there any API or Interface Table available to load data into MRP_FORECAST_DESIGNATOR
There is no interface available as of now for forecast designators. If the forecast designators are not going to change with every load of forecast then better define it manually once. Else you need to write custom program to create entry into mrp_forecast_designators table directly. This is what Oracle does when forecast is pushed from external system(like oracle demand planning) into MRP.
