ESS Custom Error Message from BADI
I am trying to handle a custom Error Message in the ESS US Bank screen. When the users enter some details in the Edit screen and click on Review I want to do a validation on the data that is entered and then return a custom error message back to the ESS screen and should not be navigating the Review screen.
We are still on the ESS WD Java version. I was looking for options and found that there are 2 BADI's which can be used but am not sure which one is the right one to handle.
Can someone point in the right direction?
