Dear Fellows,
I am hadling a problem in the Invoice Entry for Internal Orders. Error message FMUP127 appears and I am trying to follow SAP note 1576645 instructions.
It says that I got to change derivation of FM account assignment at FMDERIVE so that, as early as the RWIN-event CHECK, the correct account assignment can be derived and it is subsequently no longer necessary to overwrite them.
Honestly I donu2019t understand this instruction. Exactly how can I do this? What and where are the changes suggested at FMDERIVE? Does anybody can help me up with this?
Rgds,
Gustavo.
