Plan only raw materials during MRP run for PR creation

[PrakashD1]

Hello Experts,

I have an unusual requirement from the client. Their whole subcontractor network changed a lot which requires config change for running MRP accurately. But due to ongoing S4 conversion all configs will be frozen for next few months in ECC. To deal with this, we created an Excel tool to run the MRP based on SAP extracts and it is working satisfactorily.

Only problem is dozens of purchase requisitions for RM have to be created manually after the Excel MRP tool calculates the raw material requirement. Is there a way to run MRP just for these raw materials (PR related master data in SAP is correct)?

Possible solutions I can think of: 1. Create PIRs for these raw materials using LSMW and run MRP for them (complex)

2. Any way to mass create PRs in SAP?

Your opinion on fulfilling this?

Regards,

Divya Prakash

Hello divyaprakash

The correct way implement MRP planning for raw materials only in classical MRP is to use the user-exit M61X0001 and the user exit key and parameter fields in MD01:

The logic in the user-exit should check if a material is a raw material and suppress planning if it's not.

I'm not sure if given S/4HANA conversion you are able to implement that.

If not, the only way I see is to plan each material individually with MD03 and to automate this process with an LSMW.

Hello

If you are using S/4HANA, you don't even need to create an LSMW to upload PIRs, as the Fiori app Maintain PIRs allows you to create PIRs based on an LSMW.

Also, in MD01N you can select which specific materials will be planned, so you wouldn't need to implement any user-exit for this purpose.

Hello Caetano,

Unfortunately, S4 is still not deployed and my question is related to ECC. Any suggestions on how to do this in ECC?

That's the moment where you realize that there are lots of things that you can easily do in S/4HANA that will require enhancements in ECC 😄

I would follow the suggestions given by Dominik above, in order to run MRP for selected materials using the exit.
