MM error - Deficit of PU IR

Question

Dear experts,
I am facing an error when doing GR reversal as follows
Deficit of PU IR quantity xxxxx PC
the below solutions from the forums did not help.
- Check the stock type from which you are doing reversal. Example. from Quality inspection or Unrestricted stocl. Make sure in which stock quantity available. Try to reverse the stock from available stock type.
- pls check if the GR quantity is less than the reversal quantity.
Pls advice what more can be checked. Thanks in advance.

Hi!
The error message M7 021 with the text "Deficit of PU IR quantity" is sent when you use the indicator "GR-based IV" (EKPO-WEBRE) in the purchase order item and you try to cancel a goods receipt (for which an invoice has already been posted)without cancelling the invoice first.
When the "GR-based IV" indicator is set in the Purchase Order item the system is able to differenciate between the individual goods receipts. 
This means that we can indicate which specific goods receipt is being invoiced when we create the invoice in MIRO or which specific goods receipt we are reversing in a return.         
Therefore, in this scenario, you cannot cancel the receipt if the invoice has not been reversed first, as the receipt and the invoice are linked.
You have two options:
1) Either you reverse the relevant invoice first.                            
2) Or you allow the reversal of the receipt despite this existing invoice. This is made in the customizing transaction OMBZ: Flag the movement type 102 or 122 (or the one you are using in the reversal) to allow the reversal to be posted despite an existing invoice.                 
I hope this information helps you!
Best regards,
Esther.
