Reuse_alv_list_display - unable to do my own calculation in subtotal

Question

Hello experts,
  I am using reuse_alv_list_display in my report.   How can I apply a calculation formula in the subtotal for  Col D ?   I also need it display Col D on the same line as the Subtotal line.
No problem in totaling Col C using standard ALV.
For example:
   Col A,    B,   C,  D
    Pen ,    1,    2,   3
    Pen ,    5,    6,   7
Subtotal:         8     1.333    .
    Watch  3    1     2
     Watch 4    3    8
Subtotal :       4    0.57
Subtotal on   Col C is 8 (2 + 6)  which you can get from standard ALV
Subtotal on  Col D is    Total Col C / Total Col B.
  I am using event Before_line_output so i can do the calculation on subtotal for Col D.
The codes in the event are below.  THe calculation  is on v_gp%.
  loop at itab.
  case p_lineinfo-tabname.
    when ' ITAB'.
    when '  '.
       if p_lineinfo-sumindex = 1.
         tot_zcup = tot_zcup  + itab-s_zcup.
         tot_gp_amt = tot_gp_amt +  itab-s_grprofit.
       endif.
       if p_lineinfo-subtot = 'X'.
         v_gp% =   tot_gp_amt / tot_zcup .
          write:/ 'Amt ', tot_zcup, tot_gp_amt, v_gp%.
          modify it_s3_final index p_lineinfo-sumindex.
          clear: tot_zcup, tot_gp_amt.
       endif.
  endcase.
I get many AMT coming out in the report.    Pls provide guidance.
Thanks you so much,
Joyce
