As an ABAPer, you must have thought of adding your custom button to the standard ALV Grid called in your custom program. Here are the steps for achieving this goal.

TO achieve this you should copy the ‘STANDARD’ GUI status from program SAPLKKBL using transaction SE90 –>Programming SubObjects–> Gui Status.

Steps:

1). Using SE80/SE41 you can copy a GUI status from one program to another. It mentions which one in the FM’s help.
2). Create a form named like so:

Code:
*****************************************************************
* Form Set_pf_status
* Notes: Called by FM REUSE_ALV_GRID_DISPLAY
*****************************************************************
FORM set_pf_status USING rt_extab TYPE slis_t_extab.
  SET PF-STATUS ‘ZSTANDARD’.
ENDFORM. “Set_pf_status
 

In the above case the GUI status copied was named ZSTANDARD and adjusted accordingly, adding and removing the desired buttons. A button was added called ‘%DELETE’.

3). Create the following report:
Code:
*****************************************************************
* Form User_command
* Notes: Called by FM REUSE_ALV_GRID_DISPLAY
*        Detects whether the icon/button for
*        ‘Return Tag Deletion’ has been pressed. If it has then
*        detect whether any rows have been highlighted and then
*        set the delete flag.
*****************************************************************
FORM user_command USING r_ucomm     LIKE sy-ucomm
                        rs_selfield TYPE slis_selfield.
DATA: li_count TYPE I.
IF r_ucomm EQ ‘%DELETE’.
  LOOP AT %g00 WHERE mark EQ ‘X’.
    ADD 1 TO li_count.
  ENDLOOP.
  IF li_count GT 0.
    gc_delete_flag = ‘X’.
    r_ucomm = ‘&F03′. “Back arraow
  ELSE.
    MESSAGE W000 WITH ‘Please highlight the rows to be deleted!’.
  ENDIF.
ENDIF.
ENDFORM.  “User_command

As I’ve added an extra button to indicate which records should be deleted I need to identify a form to be called to process when this button is chosen.

Then when you call the ALV function you to specify the following extra details:

Code:
    call function ‘REUSE_ALV_GRID_DISPLAY’
         exporting  i_callback_program = gc_repid
                    I_CALLBACK_PF_STATUS_SET = ‘SET_PF_STATUS’
                    I_CALLBACK_USER_COMMAND  = ‘USER_COMMAND’
                    i_grid_title       = lc_grid_title
                    is_layout          = lc_layout
                    it_fieldcat        = gt_fieldcat
                    it_sort            = sort
                    i_save             = l_save
                    is_reprep_id       = l_bbs_id
                    is_variant         = l_variant
         tables     t_outtab           = %g00
         exceptions program_error      = 1
                    others             = 2.

The parameters in capitals are the extra ones that need to be added.

That should be it!
