I have the following code so far. It gives me error gd_sort is a table without header line and therefore has no component called Fieldname. I cannot add headerline to gd_sort as that will make the program to dump because of mismatch in data type. Any ideas?
      gd_sort      TYPE slis_t_sortinfo_alv,
  CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
    EXPORTING
      i_callback_program      = repid
      i_callback_user_command = 'USER_COMMAND'
      is_layout               = gd_layout
      it_fieldcat             = fieldcatalog
      it_sort                 = gd_sort
      it_events               = gt_events
      is_print                = gd_prntparams
      i_save                  = 'X'
    TABLES
      t_outtab                = i_zopen_alv
    EXCEPTIONS
      program_error           = 1
      OTHERS                  = 2.
FORM build_sort.
  gd_sort-fieldname = 'VBELN_VA'.
  APPEND gd_sort.
ENDFORM.                    "build_sort
