If quantity of the ordered item(s) does not match the quantity on the invoice you need to start the match with received Order Confirmation.
Access the matching overview by clicking on the Matching Symbol on the dashboard.
You will be taken to the PO Matching menu
Or by choosing PO MATCHING in the lower right corner when you have opened the document.
The “x” would delete the match on the delivery note.
A new match from the purchase order can be added to the delivery note by dragging and dropping the appropriate data row(s).
Save to apply all changes.
Once everything is correct the document can be validated and exported.
