JUST found a BIG error in PO/IM for 4.50. If you have more than one item on a purchase order, do a receipt and say no to receive all and only receive one item - the backordered item qty disappears from the Qty On PO in the IM_ItemWarehouse file after updating the ROG. YIKES! Have a new client on 4.50 and was having to rebuild the damn sort files in PO a LOT - and now I know why and can recreate on my 4.50. Lordy, I hope Sage jumps on this! (Just reported.)
