Custom variable for fiscal year/period

Question

Hi BW Experts,
My problem is only fiscal year/period is populated
(fiscal year and posting period is not populated) and I need to have a custom exit ...that if the user enters 006/2007 i need to have a varaible which will contain 001/2006 to 012/2006 ..i.e data for entire year.
It doesnt matter which year the user enters ...i should fetch data for the entire year
I am very weak in ABAP programming ..if any body can share their experience..I would appreicate with full points

Answer 1

Create a customer exit  variable(not ready for input) var1 with interval
var2 is a ready for input variable that take the value entered by the user.
IF I_STEP = 2.
WHEN 'var2'.
      DATA: v_mth_beg TYPE d,
                 v_mth_end TYPE d
      REFRESH e_t_range.
      CLEAR l_s_range.
      LOOP AT i_t_var_range INTO loc_var_range
               WHERE vnam = 'var1'.
        EXIT.
      ENDLOOP.
      CONCATENATE loc_var_range-low+0(4) '001' INTO v_mth_beg.
      CONCATENATE loc_var_range-low+0(4) '012' INTO v_mth_end
      l_s_range-sign = 'I'.
      l_s_range-opt = 'BT'.
      l_s_range-low = v_mth_beg.
      l_s_range-high = v_mth_end.
      APPEND l_s_range TO e_t_range.
try this out.Hope it helps.
