Formulae variable confusion/ abap routine

Question

in ods i have data like
Postingday................value1........value2
1/26/10............70.................50
1/27/10............60.................48
12/30/10............120.................55
12/31/10............10.................52
now in the report for a cube i have to show data for 3 keyfigures
1 is amount and 2nd is (Amount x Value1) 3rd is (Amount/Value2)
now the value1 and value2 changes everyday depending on what the Date is...
so today on 1/26/11 the value1 is 70 and value2 is 50
so i have to write formulae variable which fetches the value1 and 2 for Todays date...
what should be the code for customer exit for formulae variable..
something like pseudocode below
when "zvar1"
FOR 0calday = today = PostingDay in ods table /bic/azpostingdte
Seleect Value1 ..
endfunction

Answer 1

ok, you would like to do sth in the customer exits with formular variable.
formular variable : zvar. (with customer exits)  for value1.
case i_vnam.
    WHEN 'zvar'.
data: l_s_table type your tablename /bic/......
      IF i_step EQ '1'.
        CLEAR: l_s_range,
        select single *  from DB table into l_s_table
        with date = sy-datum.
        CLEAR l_s_range.
        l_s_range-low = l_s_table-value1.
        l_s_range-sign = 'I'.
        l_s_range-opt = 'EQ'.
        APPEND l_s_range TO e_t_range.
  endif.
endcase.
for value2 you do same with value1.
PS:  for amount you must treat it as a restricted kf (with a variable of customer exits, which is gefiiled with sy-datum.)
hope it helps you.
