Hi Ankit,

Declare this variable on your top include.

DATA: ok_press TYPE c.

=== in PBO Module ===

IF ok_press EQ 'X'.

LOOP AT screen.

IF screen-name EQ 'CMD_OK'.

screen-invisible = 1.

MODIFY screen.

ENDIF.

ENDLOOP.

CLEAR ok_press.

ENDIF.

=== in PAI Module ===

LOOP AT screen.

MOVE 'X' to ok_press.

ENDLOOP .

Hi,

Try like this,

in PAI,

loop at SCREEN .

if screen-name eq 'CMD_OK' .

flag = 'X'.

screen-invisible = '1' .

modify SCREEN .

endif .

ENDLOOP .

In PBO,

check the flag condition where it is again resetting.

Thanks,

hi

in PAI

module user_command

case sy- ucomm.

when ' enter ' " field which triggers the action .

f = 1. " declare the flag f as i in prog.

endcase

endmodule

In PBO

in any module for ex : module Initializa.

Module Initialize

If f = 1.

loop at screen

if screen-name eq 'CMD_OK' .

screen-invisible = '1' .

modify screen.

endif

endif

endloop

endmodule

Hi,

When u press 'ENTER' or any button , PAI is triggered and PBO after that.

Assign ur button (to be disabled) a group (say G1 to group1) in the screen itself.

Don't write Screen modification code in PAI. Write it in PBO.

Loop at screen.

if screen-group1 = 'G1'.

screen-active = 0.

modify screen.

endif.

Endloop.

Hope this helps.

Hi Ankit,

Check the value of sy-ucomm for enter.

I guess its space (' ').

Take the screen-group1 for the button as 'BTN1'.

So use code:-

At screen logic:-

PROCESS AFTER INPUT.
  MODULE modify_screen.

In PAI,

MODULE modify_screen.
 case sy-ucomm.
  when space.
    if ( screen-group1 = 'BTN1' ).    
      loop at screen.
        screen-active = 0.
        screen-invisible = 1. "to hide button from screen
      endloop.
      modify screen.
    endif.
 endcase.
ENDMODULE.

Hope this solves your problem.
