Prob in FM Derivation

[former_member128019]

Good day to all,

I have an interesting issue that is we are using derivation rule like fund center and commitment item from Cost center and Cost element respectively.

Example :

1. 104700001(Cost Center)/Cost element (401001) To Fund Center(104700001 Commitment Item ( 401001)

2. 104700002(Cost Center)/Cost element (401002) To Fund Center(104700002 Commitment Item ( 401002)

At the time of posting expenses initially Cost Element 401001 and Cost center 104700001 get debited and Fund Management account assignment derived correctly i.e. Fund Center (104700001) Commitment Item ( 401001)

But after simulation FI document user realized that cost center is wrong, then changed cost center from 104700001 to 104700002 but there was no changes in Fund Management account assignment i.e Fund center where it is wrong.

Could some advise us how to come out from this. We are looking solution like when ever changes in controlling cost object cost center after derived FM account assignment system should replace to correct fund center and Commitment Item based on derivation we maintained in FMDERIVE.

Thanks & Regards,

YK

Hi, for target field in derivation(for FM account assignments) select option Overwrite with new value.

Dear YK,

Unfortunately what you have described is the standard behaviour.

Please check the following SAP consulting note that explains this in detail and the workarounds available:

658163 Acct assignmnt change: Determinatn of new FM acct assignmnt

I believe that this answer your inquiry.
