SAP S/4HANA In-house Production and Subcontracting for the same Material

979 Views Last edit Jan 17, 2023 at 05:07 PM 2 rev

Hi SAP Experts,

Supposed that I have Finished Product A with a Production BOM. This product can be produced either in-house or via Toll Manufacturer/Subcontractor due to capacity constraints. These are my concerns:

1. I am aware of maintaining Proc. Type X in MRP2 - View but when maintaining it, I am not able to use Special Procurement Key (SPK) 30 - Subcontracting as it is assigned to Proc. Type F by default. the result is after MRP, only Purchase Requisitions will be created.

2. Cost for Material A is different when it is in-house vs. Subcon.

3. We are sending the Raw Materials to be used to our Subcontractors, and we also manage the inventory of Raw Mats in Subcon area therefore we need to maintain an MRP Area for the Subcon. So, if I use Split Valuation and maintain Proc. Type X in MRP2 View w/o maintaining the SPK - 30, after MRP Run, my components will not have MRP Elements SubReq/TrnRes.

Can you please advise what procedure should I do? Should I continue doing Split Val? Should I maintain a virtual plant for the Subcon? Should I maintain different FG Codes for in-house produced vs. subcon?

Thanks!

BR,
