Re: Issues in Old Invoice reversal after Activating FM

Hi,

IR/GR and their reversal are indeed trying to adopt the assignment from PO. So, PO assignment to FM is essential. In order to skip the error ME458 you have to apply OSS note

1869472 - Error ME458 - Account assignment cannot be change after GR / IR (in SRM or ECC side)

You have to go to OME9 and set flag account assignment to changeable for the relevant account category. You can switch it back when you are through.

Regards,

Eli
