System error: Funds management update (RFPOS,LFMOIU08) / Message no. FI057

Dear Expert

I am setting up FM for new SAP client.

- When I manually create PR (ME51N), it posible to created PR with manually input Fund & Functional Area.

- The issue occurred when I create PR from MRP. After I input Fund & Functional Area in "Account Assignment Tab" and then flag "Fixed ID" in "Quantities/Dates" Tab --> Fund & Functional Area is dissappeared from my input. There is error message = "System error: Funds management update (RFPOS,LFMOIU08)" Message no. FI057

Could you please help to advice, how to create PR from MRP with FM Account Assignment? How to set derivation rules to resolve this issue? (I tried derive Fund & Functional Area by refer to Commitment Item in PR, but Fund & Functional Area fields still blank after checking PR).

Hi Ton,

Firstly, please check whether in which position number the MRP was created purchase requisition.

I suspected that there are an inconsistent purchase requisition.

In standard the MRP created PR's have position number '10'.

Could you please check the relevant customizing?

Transaction OMI5 is where you can define the position number for MRP purchase requisitions.

Best Regards,
