Performance issue related to BSIS table:pls help

Question

Theres a select statement which fetches data from BSIS table.
As in the where clause the only key field used is BUKRS its consuming more time.Below is the code.
Could you please tell me how to improvise this piece of code.
I tried to fecth first from BKPF table based on the selection screen paramater t001-bukrs and then for all entries in BKPF fetched from BSIS.But it didnt worked.
your help would be very much appreciated.Thanks in advance.
  SELECT bukrs waers ktopl periv
         FROM t001
         INTO TABLE i_ccode
         WHERE bukrs IN s_bukrs.
SELECT bukrs hkont gjahr belnr buzei bldat waers blart monat bschl
shkzg mwskz dmbtr wrbtr wmwst prctr kostl
           FROM bsis
           INTO TABLE i_bsis
           FOR ALL ENTRIES IN i_ccode
           WHERE bukrs EQ i_ccode-bukrs
           AND   budat IN i_date.

Answer 1

Dnt go for FOR ALL ENTRIES  it will not help in this case .Do like below , you can see a lot of performance improvement.
SELECT bukrs waers ktopl periv
         FROM t001
         INTO TABLE i_ccode
         WHERE bukrs IN s_bukrs.
sort i_ccode by bukrs.
LOOP AT i_ccode.
   SELECT bukrs hkont gjahr belnr buzei bldat waers blart         monat bschl shkzg mwskz dmbtr wrbtr wmwst prctr kostl
         FROM bsis
        APPENDING TABLE i_bsis
        WHERE bukrs EQ i_ccode-bukrs
        AND   budat IN i_date.
  ENDLOOP.
I dnt know why perform is good for the above query than "bulrs in so_bukrs" .This willl help , i m sure. this approach helped me.
