Our team is scanning labels, and on the backend I ref a table to match the label with qr value.
I want to build a virtual column to warn users of possible duplicate entry. of scanned QR code., but make it just that a warning, that can either be ignored or acted upon. -
this was when someone is going down a line, if they accidentally scan the same qr twice they will get a warning (already done) or something.
I don’t know where to start?
