Hi Jurgen,
There was no price change in the PO item. There is no PIR reference in the PO also no material no.
The first GR entry was done thru FI direct posting (FB01)
Dr - Migration account 29,685.68
Cr - GR/IR account 29,685.68-
The first Inv entry was also done thru FI direct posting (FB01)
Dr - GRIR account 29,525.22
Cr - Migration account 29,525.22-
After invoice was posted difference occurs at 160.46 as invoice amount is lesser than the GR amount
The rest of the GR was done thru MIGO_GR
The rest of the Inv was done thru MIRO
I was not yet in the company during the time these transactions was posted. I can see the first invoice posted the amount is incorrect which causes succeeding GR to be incorrect.
Just recently the case was assigned to me and then user want to zero out the GR amount balance of 193,891.87 GR qty already set to zero.
Hope this additional information helps.
