The Receive Open Quantity option moves the open quantity for the selected PO line to the To Receive Quantity so that you can receive the remaining open quantity for the line.
If the Item being received is a serialized item, you should use the View/Enter Serial Numbers option (available from the More or Context Menus), to enter the serial numbers associated with the shipment.
The system will not allow you to create a Vendor ship invoice for a vendor shipment PO line for a serialized item, unless you have specified the correct number of serial numbers for the item. You will receive an error message from the program (an “incorrect serial number count error”); if you press the Invoice Vendor Shipment Button when the quantity being invoiced for a serialized item does not match the number of serial numbers entered for the item.
