I need some advice as to what is the proper way of reversing an ERS invoice. Example. I have a purchase order which the invoice was generated via ERS. Later we realized that the GR we have done was incorrect. Invoice has been issued for that GR. The FI went ahead to create a credit memo via MIRO and then the warehouse people have reverse the GR.
Is this the correct way? I did testing. When I tried to reverse the GR without cancelling the invoice, I will receive an error message that says Deficit of PU IR quantity 1.000 CRT.
Then I tried cancelling the invoice via MR8M but the system Igives me a meesage saying nvoice doc. 5105614721/2008 was created via evaluated receipt settlement
I read through some forums and some have advised that we can set the indicator at this setting SPRO-> Materials Management -> Inventory Management and Physical Inventory -> Goods Receipt -> For GR-Based IV, Reversal of GR Despite Invoice. I am not able to set this indicator as the client's environment will not allow me to do so.
Appreciate any advice.
