@kruthika did you also check in Invoiced Purchase Orders? What do you see there? is Invoiced Qty = 1 there?

Hello @Marcel.Ausan  i am not able to see those Purchase orders in Invoiced Purchase Orders screen.

Hi, 

Please see the manual supplier invoice and see the postings. You may need to review the posting proposal. 

It is entirely possible, that an AP invoice was entered for a PO, and manually posted, meaning the posting line is not truly connected to the PO receipt.   If this was truly matched, the invoice posting line would be created via a posting type (for example M18).   But if this was manually created the posting would not list a posting type.  In that case, the invoice was processed but not matched with the receipt. 

Your received not invoiced report probably has that record as it appears that the receipt was not really matched. 

Best regards, 

Thomas
