Is there a way to reverse a PO Return in Purchase Orders module for Sage 300?
Is there a way to reverse a PO Return once it has been posted and Day End Processing Ran.
No, since the Invoicing has been already done you need to raise a credit note against this return to do the same navigate to PO -> PO Transactions -> Credit/Debit Note Entry. Select the Return document and check the Credit Note total and post the same.
This would reverse the GRN. Once reversed, raise a new Purchase Order; navigate to PO -> PO Transactions -> Purchase Order Entry
If necessary, seek the assistance of Acute Data Systems to help provide assistance with this process.
