When we return items to vendors due to QC problems, we enter the negative amounts on the original PO and print the purchase order as a shipper to go with the items.  How can I get the PO to print only the lines I want - ie the open Quantities on the PO only?  I have the same problem when we do blanket PO's.  Each item has the same part number but different release dates, but when you print the PO, it shows all the lines whether received or not.
