MODIFY SCREEN.
endloop.
Please help me.
Answer:
Check wether the if condition before the screen-input = 0 is failing.. i have used below code for notification in enhancement QQMA0001 and its working fine..
* If the notification type is M4
IF V_QMART = 'M4'.
LOOP AT SCREEN.
IF SCREEN-GROUP1 = 'S2'.
SCREEN-INVISIBLE = 1.
SCREEN-INPUT = 0.
MODIFY SCREEN.
ENDIF.
IF SCREEN-GROUP1 = 'M4'.
IF SY-TCODE = 'IW23'.
SCREEN-INPUT = 0.
MODIFY SCREEN.
ENDIF.
ENDIF.
ENDLOOP.
ENDIF.
