CB forecasting

Dear Experts in CBF forecasting there is the following documentation,

PP/DS creates planned independent requirements at configured product level. The demand for individual characteristic values/combinations is not transferred initially. When the PDS is exploded, the system determines the dependent demand for the components by referring to the demand plan for the characteristic values/combinations. It creates dependent requirements for the components in PP/DS, which can be converted to production orders or purchase requisitions

My question is as follows:-

1. In my investigation, the expectation is that I would not have any BOM's the forecast is for a car, of colour black and engine size 2.0 ltr. Can I create a requisition to match this combination or would the requisition be for a car only. Apologies the simplified supply chain is that I generate forecast for a car, however send the basic supply plan to the vendor (my supplier).

    Hi Paul

    Assuming you are the car manufacturer, you would forecast with characteristics at a Car + Characteristic level. So with CBF, you would eventually have a forecast for a Black Car with a 2.0 engine. And another forecast for a black car with a 1.5 engine and so on. At this point, you dont need a BOM.

    You then release forecast (with characteristics) to PPDS. Even here, you dont need a BOM.

    But when you run the PPDS plan, it uses the Super BOM (VC BOM) with object dependencies to come up with a component supply plan. This is what you would use to make/ buy components.
