DATA: struct_gridsort   TYPE lvc_t_sort WITH HEADER LINE,
      i_sort_fcat    TYPE lvc_t_sort.
IN PBO,
PERFORM sort_outtable CHANGING i_sort_fcat.
FORM sort_outtable CHANGING p_i_sort_fcat.
  struct_gridsort-fieldname = 'YEAR'.
  <b>struct_gridsort-up       = 'X'.</b> (for sorting)
APPEND struct_gridsort TO i_sort_fcat.
  CLEAR struct_gridsort.
  struct_gridsort-fieldname = 'MONTH'.
  struct_gridsort-up       = 'X'.
<b> struct_gridsort-subtot    = 'X'</b>.(SubTotal)
  APPEND struct_gridsort TO i_sort_fcat.
  CLEAR struct_gridsort.
ENDFORM.                    " sort_outtable
