The header aka OCR doesn't pick up on a duplicate invoice number
I'm new to SAP Concur user community and I learned through training in my new company that SAP Concur does not pick up on the duplicate input of an invoice number therefore causing duplicate if not multiple work on entering a given invoice. The error comes after all info and coding is inputed. Is there a way to have SAP Concur 'error' out as the duplicate is being entered at the header aka OCR level???
