Hi Murali,

In your code i guess the modify screen statement missing. just add the modify screen statement within the loop screen and try

loop at screen.
 if screen-group1 = 'GR'.
 if sy-ucomm = 'CHANGE'.
 screen-input = 1.
else.
 screen-input = 0.      " when clicked DISPLAY button.
endif.
endif.
modify screen. " add line here
endloop.

Hi Niraj,

I tried with modify screen as you suggested. But no solution.

Here one thing I need to make clear. Here Iam using TabStrip. The tabstrip control exits in screen 320. For this I declared a subscreen in the screen 340. Here in 340, the table control is there.

The push buttons DISPLAY and CHANGE are in screen 320. For these push buttons Iam writing the disable and enable functionality.

I think, If Iam able to identify the tablecontrol field in screen 320, the problem will be solved.

Screen Group ' GR ' is already used for another internal table for screen 320.

Do I need to use another Screen Group for my table control?

Also please make me clear about the difference between screen-group1

screen-group2

screen-group3

screen-group4

Thanks and regards,

HAI Murali,

Make some small change in ur code..Make the Active attribute of Screen to 0.

loop at screen.
 if screen-group1 = 'GR'.
 if sy-ucomm = 'CHANGE'.
 screen-input = 1.
else.
 screen-active = 0.    " Add this line to ur code here
 screen-input = 0.      " when clicked DISPLAY button.
endif.
endif.
endloop.
