I am working with 2 screens, the second screen is a pop-up called by pressing a button on first(orders screen extended using user exits). Before calling 2nd screen, it goes through some validations and are done in the user exits.
If i press the button on 1st screen, without selecting the item line, it raises a error as required
2) if button is pressed along with item line and is not valid it again raises the error as required
The problem is, after the error, the screen freezs and i am un able to de- select the line and select the other to process.
How to solve this issue.
