Customer exit error

Question

Hi gurus,
In the debugger I looked at e_t_range and saw all 3 value lines.
how to get these values in the query. Can any one give the code for this.
thanks in advance.

Hi Rakesh,
thanks for reply,
i have created a customer exit variable for calculating the demand variability quantity.
for that in the selection screen of the query i am taking the plant, material and date values. ( plant and material are multiple sigle values and date field is interval)
this is the code for customer exit:
WHEN 'ZPRDEMVA'.
    IF i_step = 2.
      READ TABLE I_T_VAR_RANGE INTO LOC_VAR_RANGE
      WITH KEY VNAM = 'ZPRRNDT'.
      v_date = LOC_VAR_RANGE-LOW.
      v_year = v_date+0(4).
      v_month = v_date+4(2).
      v1_date = v_date+6(2).
      v3 = v_year - 1.
      v4 = v_month - 1.
      if v4 = 00.
        v4 = 12.
        v3 = v3 - 1.
      endif.
      concatenate v3 v4 v1_date into ddate.
      CALL FUNCTION 'DATE_GET_WEEK'
        EXPORTING
          DATE         = ddate
        IMPORTING
          WEEK         = zweek
        EXCEPTIONS
          DATE_INVALID = 1
          OTHERS       = 2.
      CALL FUNCTION 'WEEK_GET_FIRST_DAY'
        EXPORTING
          WEEK         = zweek
        IMPORTING
          DATE         = monday
        EXCEPTIONS
          WEEK_INVALID = 1
          OTHERS       = 2.
      sunday = monday + 6.
      v3_date = monday.
      v4_date = sunday.
      LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE
              WHERE VNAM = 'ZPRPLNML'.
        CLEAR L_S_RANGE.
        v_werks          = LOC_VAR_RANGE-LOW.
        LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE
                WHERE VNAM = 'ZPRMATML'.
          CLEAR L_S_RANGE.
          v_matnr          = LOC_VAR_RANGE-LOW.
          data: dummy_menge like i_mseg-menge value '0.01'.
          Do 52 times.
            select MATERIAL PLANT QUANT_B MOVETYPE
                  from /BIC/AWINO0100 into  table  i_mseg
                  where PSTNG_DATE between monday and sunday
                  and   MOVETYPE between 261 and 262
                  and   MATERIAL = v_matnr
                  and   PLANT = v_werks.
            if sy-subrc NE 0.
              i_mseg-menge = '0.01'.
              i_mseg-matnr = v_matnr.
              i_mseg-werks = v_werks.
              i_mseg-bwart = '261'.
              append i_mseg.
            endif.
            loop at i_mseg.
              itab1-matnr = i_mseg-matnr.
              itab1-werks = i_mseg-werks.
              itab1-menge = itab1-menge + i_mseg-menge.
              itab1-bwart = i_mseg-bwart.
              COLLECT i_mseg into itab1.
            endloop.
            sort itab1 by matnr werks bwart.
            loop at itab1 where bwart = '261'.
              itab2-matnr = itab1-matnr.
              itab2-werks = itab1-werks.
              itab2-bwart = itab1-bwart.
              itab2-menge = itab1-menge.
              read table itab1 with key matnr = itab2-matnr
                                        werks = itab2-werks
                                        bwart = '262'.
              if sy-subrc = 0.
                itab2-menge =  itab2-menge - itab1-menge.
              endif.
              append itab2.
            endloop.
            clear itab1[].
            refresh itab1.
            sunday = sunday + 7.
            monday = monday + 7.
          ENDDO.
          loop at itab2.
            sum1 = sum1 + itab2-menge.
          endloop.
          average = sum1 / 52.
          loop at itab2.
            sum2 = sum2 + ( ( itab2-menge - average ) *  ( itab2-menge - average ) ).
          endloop.
          sum2 = sqrt( sum2 / 52 ).
          l_s_range-sign = 'I'.
          l_s_range-opt = 'EQ'.
          l_s_range-low = sum2.
          append l_s_range to E_T_RANGE.
          clear itab2[].
          refresh itab2.
          sum1 = 0.
          sum2 = 0.
          monday = v3_date.
          sunday = v4_date.
        ENDLOOP.
      ENDLOOP.
    ENDIF.
here my problem is when i execute a query with single plant and material then i am getting the demand variability quantity in the report. but when i execute a query with multiple single plant or materia values, the output it is giving the same value to all the combinations of plant and material.
thanks
