I knew that the following statements allows user to by pass all the screen validations, so to achieve this we have to declare a function code in SET PF-STATUS of type Exit Command. So, my doubts r,
1- Anyway, we r adding the AT EXIT-COMMAND as a suffix to to Module statement, so again What is the necessity declaring in the SET PF-STATUS as a function code?
PROCESS AFTER INPUT.
MODULE USER_COMMAND_0200 AT EXIT-COMMAND.
2- What else wuld do the above statement apart from overcoming the validations(coz the author has mentioned this statement - ''An Exit-command allows you to insert functionality into the PAI that by passes all screen validation '', Which is I dont understand!)?
