CB forecasting

Question

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).

Rishi,
some background, the limitations are within the project, currently the manufacturer will remain on a legacy system, however the requirement is to provide the following:-
1. Capture the sales forecast from various distribution points (car dealers), this is for a car model and body type let's say
2. convert this to a requirements forecast, hence if the leadtime for manufacture is 4 weeks, your requirements forecast is date -  weeks, reflecting current stock and any production profiling such as number of days cover.  Send this to the supplier.
3. receive back from the supplier/manufacturer an agreed manufacturing plan indicating what can be produced by month, same level as above
4. Diaggregate and then add more characteristics to the demand, which would be things such as engine size, alloy wheels etc
5. Eventually release this demand to PPDS and generate purchase requisitions, the expectation is that the requisitions will mirror the PIR which has any and all the characteristics added via the demand planning process.
6. Send this purchase requisition to the supplier to confirm the request and who will receive the car when built.
Appreciate any feedback you have on this?  although not a typical approach, the project scope is determining the fact that production planning is outside our scope.  Hence only using PPDS to generate the requisitions as a means to confirm a proposed production plan.
