I have few cases where GR is done wrongly because the PO has been raised with the wrong price per quantity. the IR is done with the correct amount. Hence, we have a difference between the GR and IR amount. it's also worth noting that the GR and IR is done 2 months ago already.
I would be thankful if you could advice me on how to solve this issue.
many thanks in advance!
Some companies prefer to correct the purchase order so that the amendment will go through the original approval process.
You can use MRBR for quantity differences, however, these differences will still remain on the GR/IR account, and if due to an incorrect goods receipt, your stock and moving average price may not get corrected.
Finally, MR11 writes off the amount on the GR/IR account, (when no more invoices or goods receipts are expected) without adjusting current stock quantities.
Hope that helps to clarify your topic.
