by using user exit i validate the values which is entered by enduser.
when user press SAVE button .. user exit triggers and validate the values, if condition fails show a error message in status bar.
the problem is when user press BACK button ... user exit triggers, if condition fails.. a popup error coming instead of in statusbar. in popup only exit button is there... when exit then out of t-code.

even when user press 'EXIT' button then error comes in status bar.
