    Avoid Duplicate


      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.
