How to make this select statement faster?

Question

this statement is really taking long time to process.
in bseg table as vbeln is not primary key or seconday key, i guess thz the reason it is taking so much time ,,,
can anyone help me to sort this out... ??
any fun mod to get the data of bseg cluster table by giving vbeln?/
or any other conditions to reduce the processing time?
clear t_vbrkvbrp.
sort t_vbrkvbrp by vbeln.
loop at t_vbrkvbrp.
at new vbeln.
select bukrs belnr vbeln
       from bseg
       into corresponding fields of table t_temp
       where bukrs = t_vbrkvbrp-bukrs
        and vbeln = t_vbrkvbrp-vbeln.
endat.
endloop.
SELECT bukrs belnr buzid koart shkzg dmbtr vbeln hkont kunnr werks
       FROM bseg
       INTO TABLE t_bseg
       for all entries in t_temp
       WHERE hkont IN s_hkont
       AND bukrs = t_temp-bukrs
       AND belnr = t_temp-belnr
       AND buzid = ' '
       AND koart = 'S'
       AND shkzg = 'H'.
i need to get the g/l account number for the above condition type so i have to use bseg table

Shahid,
Usually BSEG SELECTs are slow as it is a Clu8ster table. More over you are not passing the PKeys in the WHERE condition. That's alcso one reason for slow retrieval. You can also use the table BSIS (Accounting: Secondary Index for G/L Accounts) for the G/L accounts. But first of all, I suggest you cnange your where condition as below:
SELECT bukrs belnr buzid koart shkzg dmbtr vbeln hkont kunnr werks
FROM bseg
INTO TABLE t_bseg
for all entries in t_temp
WHERE  bukrs = t_temp-bukrs
AND belnr = t_temp-belnr
AND buzid = ' '
AND koart = 'S'
AND shkzg = 'H'
<b>AND hkont IN s_hkont.</b>
Not much diff. I just re-ordered the condition based on the order of BSEG fields... Lemme know if it helps.
Regards,
Karthik
