Using SAP exit EXIT_SAPLRRS0_001

Question

Hi all,
My requirement is to calculate a query variable value based on the value of 2 other variable values , say i require to calculate "V3 = V1 + V2 ".
In this exit's include - ZXRSRU01, i use
CASE i_vnam.
WHEN 'V3'.
"    LOOP AT i_t_var_range INTO lw_loc_var_to
         WHERE vnam = 'V1'.  " => what i assumed was that lw_loc_var_to-low will hold the actual value of the variable. But this is not the case in real scenario .
I would like to know how do we access query variable values inside the include of this exit ?
Kindly help me solve the issue if you have tried the same.
Thank you all in advance,
Regards,
Asha

HI asha,
you can do one more thing..
populate value of V1 and V2 normally in I_STEP =2 and
calculate V3 in its I_STEP = 3 and use global variables
Code for Such variable is:
INCLUDE ZXRSRU01 *
DATA: L_S_RANGE TYPE RSR_S_RANGESID.
DATA: LOC_VAR_RANGE LIKE RRRANGEEXIT.
CASE I_VNAM.
WHEN 'V1'.
    IF i_step = 2.
      LOOP AT i_t_var_range INTO loc_val_range
                     WHERE vnam = 'v1char'.
        EXIT.
      ENDLOOP.
      IF sy-subrc EQ 0.
        loc_val_range-low = l_s_range-low.
        gl_variable  = loc_val_range-low ''''gl_variable is global variable
      ENDIF.
      l_s_range-sign = 'I'.
      l_s_range-opt = 'EQ'.
      APPEND l_s_range TO e_t_range.
    ENDIF.
WHEN 'V2'.
    IF i_step = 2.
      LOOP AT i_t_var_range INTO loc_val_range
                     WHERE vnam = 'v2char'.
        EXIT.
      ENDLOOP.
      IF sy-subrc EQ 0.
        loc_val_range-low = l_s_range-low.
        gl_variable2  = loc_val_range-low ''''gl_variable2 is global variable
      ENDIF.
      l_s_range-sign = 'I'.
      l_s_range-opt = 'EQ'.
      APPEND l_s_range TO e_t_range.
    ENDIF.
WHEN 'V3'.
    IF i_step = 3.
      l_s_range = gl_variable + gl_variable2
      l_s_range-sign = 'I'.
      l_s_range-opt = 'EQ'.
      APPEND l_s_range TO e_t_range.
    ENDIF.
ENDCASE.
