PO-BOM in Purchase Order

Dear MM Consultant,

My company is an IVD industry. Our affiliates will buy instruments from HQ office (intercompany). We have different configurations in the instrument products. We need to build a PO-BOM to explode the BOM which standard SAP cannot work (only Subcontracting process).

Below are the requirements:

1. Build BOM explosion in Purchse Order (Analysis how many sets are bought from HQ Office)

2. Pricing

    Buy individual items, it will be more expensive on a full set of the instrument.

Below is the scenario:

For example:

Option A (Buy from Parent)

Main Instrument = $2500

Instrument A : $1000

Instrument B : $2000

Option B (Buy from Child)

Main Instrument = $3000

Instrument A : $1000

Instrument B : $2000

3. Able to goods receipt the child and sell at child

- Consideration of Cost of Inventory (PPV) and COS

Please advise.

Thank You.
