How to: Undo Quantity Posting on Posted Return Receipts
If you have made an incorrect quantity posting, that is if you have made a return order with, for example, the wrong number of items and posted it as received but not invoiced, you can undo the posting.
To undo a quantity posting
In the Search box, enter Posted Return Receipts, and then choose the related link.
Open the relevant posted return receipt, and select the line or lines you want to correct.
On the Lines FastTab, choose Actions, choose Functions, and then choose Undo Return Receipt.
A corrective line is inserted in the posted document and the Returned Qty. Received and Return Qty. Rcd. Not Invd. fields on the return order are set to zero. If the quantity was received in a warehouse receipt, a corrective line is inserted in the posted warehouse receipt and, if the quantity was only partially received, the Qty. to Receive is updated on the warehouse receipt.
Go back to the return order, and on the Actions tab, in the Release group, choose Reopen to reopen it.
Correct the entry in the Quantity field and post the order.
