Hi All,


I have a system for Storing PO Numbers and their corresponding Invoices.


Sometimes I entered an Invoice Number twice to a two different PO Numbers.


Can you please share your expertise how to detect and avoid duplicating the same Invoice Number to a two or three different PO Numbers.


Any help is highly appreciated


Thank you.
