hi,,,,
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
I_CALLBACK_PROGRAM = sy-repid >>>>>>>>>>>>> your report name.
regarding logo and header,,,,
first store the logo in T-code OAOR, then call that in your report.......
data: heading        TYPE slis_t_listheader,
      wa_header      TYPE slis_listheader,
     events         TYPE slis_t_event.
* To display TOP_OF_PAGE.
FORM top_of_page.
  DATA : text(40),txtdt(40).
  CLEAR l_string.
  l_string = 'JCB India Limited'(hd2).
  wa_header-typ  = 'H'.
  wa_header-info = l_string.
  APPEND wa_header TO heading.                              " index 1.
  CLEAR l_string.
  WRITE :'Number of records:' TO text,dbcnt TO text+20 LEFT-JUSTIFIED.
  wa_header-typ  = 'S'.
  wa_header-info = text.
  APPEND wa_header TO heading.
  CLEAR l_string.
  wa_header-typ  = 'S'.
  WRITE : 'Report Run Date  :' TO txtdt,sy-datum TO txtdt+20 DD/MM/YY.
  WRITE sy-datum TO dat DD/MM/YY.
  wa_header-info = txtdt.
  APPEND wa_header TO heading.
  CALL FUNCTION 'REUSE_ALV_COMMENTARY_WRITE'
    EXPORTING
      i_logo             = 'ENJOYSAP_LOGO'
      it_list_commentary = heading.
  CLEAR heading.
ENDFORM.                    "top_of_page
to execute top-of-page you have to create events.
for ex......
FORM create_event USING p_events TYPE slis_t_event.
  DATA: ls_event TYPE slis_alv_event.
  CALL FUNCTION 'REUSE_ALV_EVENTS_GET'
    EXPORTING
      i_list_type = 0
    IMPORTING
      et_events   = p_events.
  READ TABLE p_events WITH KEY name = slis_ev_top_of_page
                           INTO ls_event.
  IF sy-subrc = 0.
    MOVE formname_top_of_page TO ls_event-form.
    APPEND ls_event TO p_events.
  ENDIF.
ENDFORM.                    " create_event
