I created a project in CMOD to post a billing document to COPA ( accounting)
In the include of that Project i have written code to give error messages if any logic fails.
The user exit used in the project is related to standard transaction VF02. but when i am trying to display an error message (through my code in this user exit) in VF02 ,it is not gettig displayed .
Is it <b>possible to display these error messages in standard txns using CMOD user exits</b>.
