Subtot in REUSE_ALV_GRID_DISPLAY

Question

When use fm REUSE_ALV_GRID_DISPLAY, all item is show-up. by use subtot, we can click the icons to hide all the item and just show the subtot line & total line.
Are there any parameter, List can start with the subot line and total line (item is not show-up at first), then user do not had to clik the icons?

Hai Jerry
Go through the following ways for subtotals in ALV
Refer to this similar thread.
alv Display :Total and subtotal
for sub totals you have to use
sort table.
sort-fieldname = 'VBELN'.
sort-tabname = 'ITAB'.
sort-up = 'X'.
sort-subtot = 'X'.
append sort to it_sort.
Or
Define SORT table and FIELDCATALOG table .
Data :i_field type slis_t_fieldcat_alv,
w_field like line of i_field,
i_sort type slis_t_sortinfo_alv,
w_sort like line of i_sort.
2.Grand Total
While buildingfieldcatalog,We have to set DO_SUM = 'X' for quantity field .
ex.
w_field-fieldname = 'MENGE'.
w_field-tabname = 'I_TAB'.
w_field-DO_SUM = 'X'.
append w_field to i_field.
clear w_field.
3.Subtotal
Whenever WERKS is changed Subtotal is displayed .
Build sort table .
Clear: w_sort,i_sort[].
w_sort-spos = 1.
w_sort-fieldname = 'WERKS'.
w_sort-up = 'X'.
w_sort-subtot = 'X'.
append w_sort to i_sort.
clear w_sort.
4.
Pass this I_SORT table thru REUSE_ALV_LIST_DISPLAY function module ..like fieldcatalog table.
Or
For sub totals you need to sort and pass the sort table to FM.
But for total you need to pass to field catalog like below
  fieldcatalog-fieldname   = 'NETPR'.
  fieldcatalog-seltext_m   = 'Net Price'.
  fieldcatalog-col_pos     = 7.
  fieldcatalog-outputlen   = 15.
  fieldcatalog-do_sum      = 'X'.       "Display column total
  fieldcatalog-datatype     = 'CURR'.
  append fieldcatalog to fieldcatalog.
