I need to check for the invoices with the combination of reference number and the amount. If both are matching then the system should give the warning message

Hai

In vendor Master Data there is a check box called Check Dupluication of invoices.You have to keep that field as mandatory for all vendors..

At the time of posting f-43 if any invoice number is repeated system will throw a warning message that already the invoice number exsists.You have to double click that message and check the application area and message number and go there and change the warning message to error message.simple your client reqt will be met.

Hi AA,

All that you need to do is that, goto document type in TCode OBA7 and for the document type KR and for all other documents which are vendor related, you need to flag the "Reference Number" Checkbox.

In the reference field, the client generally enters the physical invoice number of the vendor invoice.

Once an invoice is posted say with refernce number ZA1 and saved, the system automatically throws an error message when the client tries to post another invoice with the same reference number to the same vendor once again there by avoiding any duplicate invoices being posted.

Hope this answer helps you. Please assign points if found useful.
