Purchase Order Row UDF for Received Qty

Question

Hi experts,
Can someone please recommend a way to create a row UDF for purchase orders to show the qty received? We cannot use a simple calculation like Qty-Open Qty because if the row is closed manually, the open qty becomes zero. Another problem is how to prompt the PO to update this value if additional GR PO's or AP Invoices are created. Thanks.

Answer 1

I should explain the circumstances more clearly. There is no problem with the standard GR PO or AP invoice receiving method. What I want is a reference field on the original PO showing the total qty received to date. For example: total of 1,000 pcs ordered -> 900 pcs received against several GR PO's -> want to see that 900 has been received back on the PO. Then let's say we want to close the PO line 100 pcs short.
I can think of 2 ways to go about this:
Method 1: Change the ordered qty from 1,000 to 900 -> row is closed, but lose the reference of the original order qty being 1,000.
Method 2: Close row manually and maintain the original order qty as reference, but lose b/o qty and it is difficult to tell how many pcs where received/closed short.
Is there another way to keep all the reference information?
