Hi Priyaranan,

Please do the change in INVISIBLE attribute as shown below.

 LOOP AT SCREEN .

       IF SCREEN-NAME = 'STUD_ID'.
         SCREEN-OUTPUT = 1.
         SCREEN-ACTIVE = 1.
 *        SCREEN-INVISIBLE = 1.
         SCREEN-INVISIBLE = 0.
         MODIFY SCREEN.
       ENDIF.

       IF SCREEN-NAME = 'ZSTUD_ADD-STUD_ID'.
         SCREEN-OUTPUT = '1'.
         SCREEN-ACTIVE = '1'.
*         SCREEN-INVISIBLE = '1'.
         SCREEN-INVISIBLE = 0.

Hi Priyaranjan,

Also add the following coding in PBO.

PROCESS BEFORE OUTPUT:
IF SY-UCOMM = 'GO'
LOOP AT SCREEN.
     IF SCREEN-group1 = 'GRP'.
       SCREEN-INPUT = 1.
       SCREEN-INVISIBLE = 0.
     ENDIF.
     MODIFY SCREEN.
ENDLOOP.

ELSE.

LOOP AT SCREEN.
     IF SCREEN-group1 = 'GRP'.
       SCREEN-INPUT = 0.
       SCREEN-INVISIBLE = 1.
     ENDIF.
     MODIFY SCREEN.
   ENDLOOP.

ENDIF.

Thank you so much.

Its working now, but when i am clicking on button PAI is getting trigger.

pai code should work.

Why please let me know the reason.

[jyotirmaya_mallick]

its simple, the screen flow is

PBO->PAI->PBO->Output(Screen).

so if you do any screen changes in PAI, it will changed in PBO, then screen display.

So any changes in Screen is done on PBO.

I think it will clear your doubt

Thanks,

Jyoti

Hi Priyaranjan,

any screen modification can only be done on the PBO.

you need to move the PAI codes to PBO.

Thanks,

Hello PRIYARANJAN,

Try this.

Global variable.

data gv_hide.

In PAI

if sy-ucomm = 'GO'.

  gv_hide = 'X'.

endif.

In PBO

IF gv_hide = 'X'

LOOP AT SCREEN.
     IF SCREEN-group1 = 'GRP'.
       SCREEN-INPUT = '0'.
       SCREEN-INVISIBLE = '1'.
     ENDIF.
     MODIFY SCREEN.
   ENDLOOP.

ENDIF

I hope you help.

Hi priya

PROCESS BEFORE OUTPUT

module change_screen.

______________________________________________

module change_screen output.

if sy-ucom = <button_name>

loop at screen.

if screen-name = <field_name>.

     screen-active = 0.

     screen-invisible = 1.

modify screen.

endif.

endloop.

endif.

endmodule.
