reg. module pool....have ur points..
In module pool programming, we see "MODULE CANCEL AT EXIT-COMMAND" in PAI. Pleas let me know the meaning of this in simple language.....
<b>n Have ur points.</b>
Let me explain this clearly to you.
Let us assume,U r using a Screen.
In this screen,U are using a back button i.e., GUI status for BACK,and this is of EXIT type(E).
and U have made a field on the screen as mandatory (using attributes in screen painter).
Now,when u try to go out of this screen using the back button.U will get an error message<b>(Fill in all required fields)</b>
Now,our module <b>ON EXIT COMMAND</b> comes into play.
If this module is prsent in our code.It overtakes control from the mandatory filed and allows U to move out of screen using the BACK button(coz it is of EXIT type)
