    Avoid Duplicate

    thong127

      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.
