Select statement from bkpf slows down the system

Question

hi guys,
i have this syntax for this coding:
        SELECT * FROM bkpf
         WHERE bukrs = ekko-bukrs
           AND awkey = xawkey
           AND gjahr = i_ir-budat(4)
           AND blart = 'RE'.
        CLEAR: titab.
        titab-ebeln = itab-ebeln.
        titab-ebelp = itab-ebelp.
        titab-budat = bkpf-budat.
        titab-bldat = bkpf-bldat.
        titab-xblnr = bkpf-xblnr.
        APPEND titab.
     ENDSELECT.
this coding really slows down the report seleection and sytem , can anybody advice on how to select the better way

Hi Ester,
First you need to avoid the select and endselect statement by using SELECT INTO TABLE.
Second issue is u are using non-key fields in where conditions are aweky, belnr  and u r not using the belnr which is first key-field in the BKPF table.
Third one is try to use the fields in correct order which it is in table say in ur where codition it should be like bukrs, gjahr, blart, awkey,....
if you dont have a input field BELNR and u need to do really improve the performance with these input fields wht you have, its is better to create Secondary index with proper sequence for felds.
But i am not sure to give permission to create secondary index bec it takes more memory occupation like what exact BKPF tbale contains, you need to permission from client people along with BASIS people.
i am give sample code  :
SELECT * FROM bkpf  " try to specify the internal table with exact fileds instead '*'
    into table tbl _ bkpf
WHERE belnr = w_belnr
and    bukrs = ekko-bukrs
AND gjahr = i_ir-budat(4)
AND blart = 'RE'.
AND awkey = xawkey.
If sy-subrc = 0.
sory tbl_bkpf by belnr.
endif.
Let me know if any doubts.
