Hi Nitin,
I dont think this can be achieved via just EVENTS!...
Go to SM30 --> Change --> (Menu) System ---> Status .. Double click on the 'Screen Number' - you would be forwarded to the Screen Logic.
In the PBO Section, Within the LOOP at SCREEN on that screen-field name., Check whether the 'Check' is done, if yes then make screen-active = '0'.
Hope this helps.
Cheers,
Kripa Rangachari.
