Need help in using a Secondary Index of a GL Table

Question

Hello ABAPers,
Good morning/afternoon!
I  was wondering if anyone could give me a hand on this issue.
To give you a brief background, I need to retrieve Open and Cleared items in the last 24 hours, that is, from 11 am yesterday till 10:59:59 today. The criteria is to pull the information using Entry Date (CPUDT) and Entry Time (CPUTM) from BKPF and using BELNR, retrieve the postings in BSIS and BSAS. as you can see in the piece of code. However, this process takes soooooo long to run.
Below is the code snippet.
We use 46C and MS SQL database.
The index fields of BKPF~ZB2 are: MANDT, CPUDT and BLART.
The index fields of BSIS~Z01are: BUKRS, GJAHr, HKONT, PRCTR, GSBER
TYPES: BEGIN OF i_bseg,
       bukrs LIKE bkpf-bukrs,
       hkont LIKE bsis-hkont,
       gjahr LIKE bkpf-gjahr,
       belnr LIKE bkpf-belnr,
       buzei LIKE bsis-buzei,
       bldat LIKE bsis-bldat,
       budat LIKE bsis-budat,
       waers LIKE bsis-waers,
       monat LIKE bsis-monat,
       shkzg LIKE bsis-shkzg,
       gsber LIKE bsis-gsber,
       dmbtr LIKE bsis-dmbtr,
       wrbtr LIKE bsis-wrbtr,
       cpudt LIKE bkpf-cpudt,
       cputm LIKE bkpf-cputm,
       END OF i_bseg.
*Internal Tables
DATA:
      i_bkpf TYPE TABLE OF bkpf,
      i_bseg TYPE STANDARD TABLE OF i_bseg.
Select records from yesterday's entry date.
    SELECT  bukrs belnr gjahr monat budat cpudt cputm waers
            FROM bkpf INTO  CORRESPONDING FIELDS OF TABLE i_bkpf
            WHERE ( cpudt = so_date2-low AND
                    cputm >= so_cputm-low AND
                    cputm <= so_cputm-high )
            OR    ( cpudt = so_date2-high AND
                    cputm >= so_time2-low AND
                    cputm <= so_time2-high )
            %_HINTS MSSQLNT 'INDEX("BKPF" "BKPF~ZB2")'.
    IF sy-subrc NE 0.
      MESSAGE e006 WITH 'BKPF'.
    ENDIF.
Select Open Items***
    SELECT bukrs hkont gjahr belnr buzei  budat bldat
           waers monat shkzg gsber  dmbtr wrbtr
           FROM bsis
           APPENDING CORRESPONDING FIELDS OF TABLE i_bseg
           FOR ALL ENTRIES IN i_bkpf
           WHERE bukrs = i_bkpf-bukrs
           AND gjahr = i_bkpf-gjahr
           AND hkont IN so_saknr
           AND belnr = i_bkpf-belnr
           %_HINTS MSSQLNT 'INDEX("BSIS" "BSIS~Z01")'.
Also get any cleared items ***
    SELECT bukrs hkont gjahr belnr buzei  budat bldat
           waers monat shkzg gsber  dmbtr wrbtr
           FROM bsas
           APPENDING CORRESPONDING FIELDS OF TABLE i_bseg
           FOR ALL ENTRIES IN i_bkpf
           WHERE bukrs IN so_bukrs
           AND   hkont IN so_saknr
           AND   gjahr = sp_gjahr
           AND   belnr = i_bkpf-belnr.
Many thanks,
Rosemarie

Thanks for your response.
The date and time fields are defined in my selection screen and the default values pre-set in the INITIALIZATION, so the dates and times are already stored as a range.
The problem is why is the process taking so long. Is the syntax for the INDEX correct?
PARAMETERS:p_not RADIOBUTTON GROUP pass.
SELECT-OPTIONS:
  so_date2 FOR bkpf-cpudt,         " Entry Date
  so_cputm FOR sy-uzeit,         " Entry Time
  so_time2 for sy-uzeit.        " Entry Time 2
INITIALIZATION.
RANGES: so_time2 FOR sy-uzeit.
  g_date = sy-datum - 1.
  g_year = sy-datum+0(4).
  sp_gjahr = g_year.
  CONCATENATE sp_gjahr '0101' INTO g_from_date.
  g_from_time = '110000'.
  g_24_hour   = '235959'.
  g_time_diff = g_24_hour - g_from_time.
  g_to_time = g_from_time + g_time_diff.
  g_to_time2 = g_from_time - 1.
  MOVE: 'I'      TO so_cpudt-sign,
        'BT'     TO so_cpudt-option,
        g_from_date   TO so_cpudt-low,
        sy-datum TO so_cpudt-high.
  APPEND so_cpudt.
  MOVE: 'I'      TO so_date2-sign,
        'BT'     TO so_date2-option,
        g_date   TO so_date2-low,
        sy-datum TO so_date2-high.
  APPEND so_date2.
  MOVE: 'I'         TO so_cputm-sign,
        'BT'        TO so_cputm-option,
        g_from_time TO so_cputm-low,
        g_to_time   TO so_cputm-high.
  APPEND so_cputm.
  MOVE: 'I'         TO so_time2-sign,
        'BT'        TO so_time2-option,
        '000000'    TO so_time2-low,
         g_to_time2 TO so_time2-high.
  APPEND so_time2.
