Blocking creation of Return PO to vendor

Question

Vendor owes us credit note on return stock. Debit amount in excess of $2000.
Is there a way to block Users from creating a Return PO back to the same vendor but allow creation of normal standard PO.
Is there a alternative way to release the block once the credit note is received?

Answer 1

Hello Colin,
Debit amount can be exceeded in two ways
1. By creating return PO
2. By creating Return delivery
Solution:
for 1: You can use the user exit as suggested by Charlie
For 2: Follow the below suggestion.
You can block the user for creating returns via mvt type (Return mvt type 122)
- Go to OMJJ t-code
- Put mvt type 122 (return delivery)
- Uncheck "RevGR despite of IR" indicator
By doing this, the user will not be able to cancle the GR or return delivery.  Please check out the following help for that indicator.
<b>Reversal of GR allowed for GR-based IV despite invoice</b>
Indicates that in the case of GR-based invoice verification  you can enter a reversal in respect of the purchase order, or a return delivery, even though the corresponding invoice for the goods receipt document has already been posted.
Hope this will resolve issue.
