Hi,
In FB60 for a non PO invoice, how can we restrict the duplicate invoice through reference number for different date and amounts. How can I create a hard error when the user posts a duplicate invoice for different amount and date. Right now the hard error is appearing for the reference num, same date and same amount.
I wanted to create a z function module and tag it to 1110 fucntion module in FIBF Tcode. But can anybody advice if any standard SAP process is available.
Thanks,
Vardhan.
