Total and Subtotal for set_table_for_first_display

Question

Hello,
I am displaying data in ALV by using set_table_for_first_display , i want to do_sum  for
10-15 columns starting from the column index 11.. and i have also passed the value in internal table of type LVC_T_SORT and in the fieldcatlog this fields are checked for DO_SUM but sum is not coming in the final output even summation button is disabled and subtotal is also getting reflected.
Is it i need to do extra to do this when i am displaying data by using the OOPS methos?
Please sugggest what could be the reason..
Thanks

Hi,
Try the below code.
TABLES: mara.
SELECT-OPTIONS: s_matnr FOR mara-matnr.
types: begin of ty_marc,
         matnr type marc-matnr,
         werks type marc-werks,
         count type i,
       end of ty_marc.
data: it_marc type standard table of ty_marc with header line.
START-OF-SELECTION.
  SELECT matnr werks FROM marc INTO TABLE it_marc WHERE matnr IN s_matnr and werks in ('0888', '0811').
  loop at it_marc.
    it_marc-count = 1.
    modify it_marc transporting count.
  endloop.
