Performance issue with BKPF and BSIS tables

Hi - I have written query like below.

SELECT bkpf~bukrs bkpf~belnr bkpf~gjahr

           bkpf~bldat bkpf~budat bkpf~monat

           bkpf~awtyp bkpf~awkey bkpf~blart

           bsis~buzei bsis~buzid bsis~shkzg

           bsis~dmbtr bsis~hkont bsis~bschl

           bsis~werks bsis~xref3 FROM bkpf INNER JOIN bsis

        ON bkpf~bukrs = bsis~bukrs

       AND bkpf~belnr = bsis~belnr

       AND bkpf~gjahr = bsis~gjahr

      INTO CORRESPONDING FIELDS OF TABLE gt_bkpf_gr

     WHERE bkpf~bukrs EQ '1000'

       AND bkpf~bldat IN s_bldat

       AND bkpf~budat IN s_budat

       AND bkpf~blart EQ 'AB'

       AND bkpf~glvor EQ 'ABCD'

       AND bkpf~xreversal EQ space

       AND bsis~hkont IN s_hkont

       AND bsis~buzid EQ 'P'

       AND bsis~werks IN s_werks

       AND bsis~dmbtr IN s_dmbtr.

gt_bkpf_gr is a Hash table. here we are always passing the Company code(BUKRS),posting date(s_budat),and G/L account(s_hkont).

For 73 entries it is taking 13 mins.Is there anyway to redesign the above query such that it will improve the performance.
