ALV Replace standard button behavior!

[Former Member]

Hi!

Can anybody explain me if its possible to replace a standard behavior of a Grid's button?

For example: I want to replace the logic of Sort button, when the user sorts the ALV I want to show a popup message.

I tried to find where the sort logic is done, but I couldn't find it.

Thanks

If you want to Override the Standard Button Behaviour you have to Use the Two events

One SET_PF_STATUS and User_command

One is for Setting the PF-status and other to Handle the Button actions

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
    EXPORTING
     I_CALLBACK_PROGRAM                = SY-REPID
   I_CALLBACK_PF_STATUS_SET          = ' STATUS'
   I_CALLBACK_USER_COMMAND           = 'USER_COMMAND '
     IS_LAYOUT                         = FS_LAYOUT
     IT_FIELDCAT                       = T_FIELDCAT
    TABLES
      T_OUTTAB                          = T_VBAP
   EXCEPTIONS
     PROGRAM_ERROR                     = 1
     OTHERS                            = 2.
  IF SY-SUBRC NE 0.
    MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
            WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.

You need to have two forms one is for Sattus and other is for User_command handling.

FORM STATUS using extab type slis_t_extab.

SET PF-STATUS 'AAAA' excluding extab.

"here you set the status, give your own okcodes to the buttons 
"like sort etc.

ENDFORM.

FORM USER_COMMAND using ucomm type sy-ucomm 
                                                selfield type slis_selfield.

"hanlde the above buttons here..

case ucomm.

when 'SORTT'.
 "Do popup here.
endcase.

ENDFORM.
