O4G1 goods receipt creates FM document with OFUP set to MM Invoice recipt

Question

Hi,
We have IS-OIl-TD (Transport and Distribution) implemented. The flow of the process is the standard TD process, first we create a PO, then we create an inbound delivery (VL31N), after that we create a bulk schedule (O4F1) for the product being imported, then we make a load confirmation (O4G1) and finally a delivery confirmation (O4H1).
When we make the load confirmation (O4G1) the system, as indicated by our IS-OIL/MM specialist, makes a goods movement, placing the product in the intransit storage location. This movement makes a credit to the GR/IR account and a debit to the corresponding stock account (inventory account). However this posting is creating a FM document through the credit to the GR/IR account with the account assignment of the stock item assigned in the PO.
We have in the OFUP customizing that the GR/IR update should be performed during the invoice reception, but somehow this goods movement is not being interpreted as a goods receipt, in fact the business transaction is RMWA instead of RMWE.
Because of the situation described above, if I have a PO for 1000$, therefore have a commitment of that amount in account assignment XX, then when we make the load confirmation (O4G1) it creates a credit to the GR/IR with the same account assignment as the PO creating a reduction of the expense for the same account assignment XX by 1000$. So at that moment I still have the PO with a 1000$ commitment and a reduction of the expense in the annual budget created by the GR/IR of 1000$. When I post the invoice the system reduces the PO commitment (as excepted) and creates a value type 54 for the $1000 of the corresponding invoice. This makes the expense on FM at a net value "zero", because at the end I have an expense reduction of $1000 (caused by the O4G1) and an expense of $1000  (caused by the invoice), which is totally unacceptable.
My question is if anyone has had this problem and if you see a possible solution to this.
I would probably want the O4G1 posting to have no effect on FM, but the use of the derivation strategy seems useless because I can't control the GR/IR account assignment derivation.
I appreciate any leads on how to find a suitable solution to this issue.
Regards,

Hi,
how you have set up the invoice generating?
If you have activated ERS, then you have to cancel the goods receipt not the invoice document. ERS will then create the relavent cancellation invoice for the cancelled goods movement.
If you have not activatd ERS then you can reverse through FB08.
Thanks
