Account Assignment change during document creation -- FMUP 127
We got the below error message no: FMUP127 while posting document using T.code:FB50
"account assignment change during document creation".
Change the FM account derivation (transaction FMDERIVE) in such a way that, for the RWIN event CHECK (this event is before the document creation of all components), the correct account assignment is derived and an overwriting is no longer necessary."
Can anyone help us to solve the issue.
