I am sending the data in MT100 format to the bank in that Transactions reference number (Tag 20) as document number. But our client copying the number ranges every year so the same document is existing in previous year also. I am getting duplicate error message from the bank when i sent the data to the bank in this year with the same document number.
Can anyone suggest for this issue. Is there any number (or) value which will be generated uniquenumber (it should not be duplicated with any number) in F110.
