Hello thank you already for your answer.
well I have a mobile terminal equipped with a barcode scanner.
I logged into my Netsuite account via mobile and tried to receive supplier orders for which I had the PO # printed.
When I position the cursor in the "SELECT ORDER NUMBER" field, and scan the PO bar code, its ID is automatically collected in this field. However the PO # is not automatically checked in the list so it is impossible to scan several PO # simultaneously.
How to deal with this limitation?
