Hi Justok,

Not sure if this is what your asking, but when I process orders against blanket open purchase orders I do something like the following using a view and a SCAN ENDSCAN:

*If PO has some parts left but not the entire amount do this
IF (shipview1.qty_ordered - shipview1.qty_shipped) - QtyToShip < 0
*get remaining parts on this PO
OldQtyToShip = QtyToShip
NewQtyToShip = shipview1.qty_ordered - shipview1.qty_shipped

*define QtyToShip for the return loop
QtyToShip = OldQtyToShip - NewQtyToShip


..........rest of processing code
