Total and Save layout in ALV grid

Hi ,

I want to display total of certain columns with sort function in ALV grid. It is coming fine but save layout  and change layout icon is not coming. if i try to give option of save layout button the total is not coming.

can you please tell me how to acieve both.

  gs_variant-report = sy-repid.

CALL FUNCTION 'REUSE_ALV_VARIANT_DEFAULT_GET'
EXPORTING
   I_SAVE              = 'A'
  CHANGING
    cs_variant          = gs_variant
EXCEPTIONS
   WRONG_INPUT         = 1
   NOT_FOUND           = 2
   PROGRAM_ERROR       = 3
   OTHERS              = 4
          .

  lv_repid = sy-repid.

  CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
    EXPORTING
      i_callback_program = lv_repid
      is_layout          = p_g_alv_layout
      it_fieldcat        = gt_field_catalog
      it_sort           = it_sortcat
      it_events         = i_Event
      i_default          = 'X'
      i_save             = 'A'
      IS_VARIANT       = gs_variant
    TABLES
      t_outtab           = lt_invoice
    EXCEPTIONS
      program_error      = 1
      OTHERS             = 2.
  IF sy-subrc <> 0.
    WRITE: / 'Error when calling ALV grid Display'.
  ENDIF.

  When i comment the parameter i_Callback_program i get total but not the save layout icon. when i uncomment i_callback_program i get save layout icon but toatl and sorting disappears.
