How can we add a button on our ALV Grid

Question

Hello,
I need to add a button on the ALV Grid and write a code on that button to download a file on the desktop of the user's machine.
How can we write a code for the same and what would be the syntax of that code.

Answer 1

Hi,
you should copy the 'STANDARD' GUI status from program SAPLKKBL using transaction SE90 >Programming SubObjects> Gui Status.
ENTER SAPLKKBL PROGRAM
STATUS STANDARD.
exexute.
select standard  check box. copy to your zprogram and your gui status.
Enter your Z program name and the name you what for this status - you can keep it as 'STANDARD' to be simple.
then go to se 38 double click on pf status .it goes to me41 screen .
there you can add your button along with predefined buttons on application toolbar.
then write code for button using user command event.
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
