Problem reg variables in BEX

Question

Hi Gurus,
I am doing sales trend reporting in bex....I have 4 key figures which all gives sales Amt created using some variables.
my Selection creteria is  calmonth/Yr
Key fig 1 - should show the sales of selected month
Key fig2 - should show the sales of selected month for prev yr
Key fig3 -should show the sales of starting of yr to selected month
Key fig4 - should show the sales of starting of yr to selected month for prev yr...
Every thin is fine...but my problem is when i give the current month how can i show my sales ?
ie (1)  Selection month = September 2007 ( which only a portion completed)
Current month:   data from 9/1/2007 thru 9/26/2007  (i.e., all the data we currently have for September)
Same month prior year:   data from 9/1/2006 thru 9/30/2006  (i.e., the data for the full month of 9/2006)
Current YTD:   data from 1/1/2007 thru 9/26/2007
Prior YTD:   data from 1/1/2006 thru 9/30/2006
Please give me ur suggestion how to create the variables for the KF 1  and KF3 ?
the coding for variable of KF3  which is used for
      LOOP AT i_t_var_range INTO loc_var_range.
        IF loc_var_range-vnam(7) = 'ZSELMON'.
          v_year = loc_var_range-low+0(4).
          v_month  = loc_var_range-low+4(02).
          CONCATENATE v_year '01'  INTO l_s_range-low.
          CONCATENATE v_year v_month INTO l_s_range-high.
          l_s_range-sign = 'I'.
          l_s_range-opt  = 'BT'.
          APPEND l_s_range TO e_t_range.
          EXIT.
        ENDIF.
      ENDLOOP.

hi Balaji,
firstly can you please confirm if your input variable is Day interval or Month interval.
ok if it is all up to ur requirement. please create a variable on cal month  to show current month or use one of the standard once.
restrict it with your KF to get your KF1.
Create a new RKF and in this use cal month variable used earlier and give a offset value 0f -12 and this gives you you KF3
please find this code for month variable it might help.
when 'ZMONTH1'.
Get the user input day from ZCALDAY
      if i_step = 2.
        read table I_T_VAR_RANGE into z_t_var_range
                        with key VNAM = 'ZCALDAY'.
        if sy-subrc eq 0.
          if not z_t_var_range-LOW is initial.
            ZE_T_RANGE-SIGN    = 'I'.
            ZE_T_RANGE-OPT     = 'EQ'.
            ZE_T_RANGE-LOW     = z_t_var_range-LOW+0(6).
          endif.
        else.
          ZE_T_RANGE-SIGN    = 'I'.
          ZE_T_RANGE-OPT     = 'EQ'.
          ZE_T_RANGE-LOW     = SY-DATUM+0(6).
        endif.
        APPEND ZE_T_RANGE TO E_T_RANGE.
        clear ZE_T_RANGE.
      endif.
