I am attempting to run a custom Z function to check specific fields against the search terms to make sure the vendor does not exist yet. I am not sure exactly where to put this call.
The function I wrote will run special logic and send back a table of possible duplicate vendors. If that table is not initial, I want it to issue an information message to user with a list of possible duplicate vendors. User can then stop the transaction or continue the save process.
I have the function written, but I am not exactly sure where I find the proper user exit to do this. Any help is appreciated.
