Duplicate vendor Invoice check in FB60
I want to put the duplicate invoice check while posting the vendor invoice through FB60. I want the system to check the duplicate invoices in combination of the Vendor code and vendor invoice number ( we put the vendor invoice no. in the reference field of FB60 ). How to make this possible. I do not want to make the FI validation for the same. Can you please suggest how to go ahead with this.

if the validation is not executed (put a break point into the code to verify), it will for sure not work. Program SAPLFIS0 is a function pool, having (among others) the oriiginal unction module FI_DUPLICATE_INVOICE_CHECK. I have explained earlier why this does not help: because of the different document dates the standard does not see this as a duplicate entry.
So if your ABAPer was not able to call the Z* function yet, you probably need to change your ABAPer ) I hardly believe that I could describe it more detailed than I did in my previous post. Go to all the steps again and make sure you do not miss anything.
Hope that helps, points welcome
