I am coding a user exit for CO02. If the user changes the required quantity in the components view and try to save it, based on the material type I need to display a error message that he cant do that.
I did all the coding but the problem is if I display it as a Error message type , after displaying it on screen if I hit back button its giving me a dump.
If I display it as a warning message type, after displaying it on screen if I hit back button its NOT giving me a dump.
Can you please explain me the reason behind it.
