Make-to-order in SAP PS

Hello!

We have a scenario in SAP PS where the client would like to use sub-contracting using PS. The finished material is assembly by a subcon while the components are either procured and physically delivered to the vendor location while the GR is done to a particular storage location. The client has a storage location for each subcon to identify who has the components etc. In order to achieve this in the subcontracting process, the "Individual/coll" indicator for the components has to be kept as "1". The problem that arises because of this configuration is that MRP does not consider any available plant stock for the components when BOM is exploded for the header material. Therefore, a PR or Pl. order gets generated for all the components irrespective of whether it is in stock or not.

Has anyone come across a similar situation?

Regards,

Kishor

Hi

It is assumed that you are running Planning with MD51. If yes then Assign Material to Project With Movement 412 Q.and Check. If Not then what strategy group you are using for MRP run.

Yes, planning is done at the plant level. Strategy assigned to the FG is 21.

I understand that 412Q will resolve this issue, however the user will have to manually check which of the components are in stock at the plant level and do this movement else MRP will create a PR or pl. order. Is there a way to avoid this or get MRP to consider that component stock is available at the plant level?

It sounds like you should maintain the components in Plant Stock rather than Project Stock. One of the basic assumptions in using Project Stock is that each projects inventory is kept separate from all other inventory during the MRP run. You can have Project Stock in Vendor Inventory but you don't have to.


The header material can be kept in Project Stock while the components are managed in Plant Stock. What are you business requirements?

I could maintain the components as plant stock but I would face the following problem.

Maintaining the components as plant stock (Indiv./Collective indicator in MRP4 = 2) means that when I am doing the GR for the header material, SAP will expect components to be available as "Stock at vendor location". However, the client wants to maintain the component stock that is physically provided to the vendor as virtual stock in a specific storage location. This is only possible if the components are maintained as individual requirements.
