hello,

TO disable a button use the logic below


DATA: it_ucomm TYPE TABLE OF sy-ucomm.

AT SELECTION-SCREEN OUTPUT.
  APPEND :
    'PRIN' TO it_ucomm,  "for print
    'SPOS' TO it_ucomm,	 "for SAVE
    'ONLI' TO it_ucomm,  "for execute
    'E' TO it_ucomm,    "for back
    'ENDE' TO it_ucomm,  "for exit
    'ECAN' TO it_ucomm.  "for cancel
 
  CALL FUNCTION 'RS_SET_SELSCREEN_STATUS'
    EXPORTING
      p_status  = sy-pfkey
    TABLES
      p_exclude = it_ucomm.

Once the button is clicked, again the above logic can be altered to enable it again.

Regards,

Mansi.

Hi,

You can disable a particular button in the GUI status by excluding that function code while setting the PF status.

Create a perform with name pf_stat_set and write this following code and pass this perform name to the parameter i_callback_pf_status_set of the ALV function module

FORM pf_stat_set USING extab TYPE slis_t_extab.

DATA: w_extab TYPE slis_extab.

w_extab-fcode = 'XXX'. "The function code of the button you want to exclude

APPEND w_extab TO extab.

SET PF-STATUS 'YYYY' EXCLUDING extab.

ENDFORM.

Thanks,
