Find cleared document according entry date of clearing document.

Question

Hi,
i have poor performance in this issue. I would find cleared document according clearing document. On selection screen are cpudt and cputm clearings documents and i need to find cleared document for these document.
First statement
select bukrs gjahr belnr into table i_bkpf from bkpf where cpudt in so_cpudt and cputm
Second statement
select burks gjahr belnr into table i_itab
for all entries in i_bkpf from bsas where bukrs = i_bkpf-bukrs
<b>and augbl = i_bkpf-belnr and augdt = i_bkpf-budat</b>
Third stat.
select burks gjahr belnr appending table i_itab
for all entries in i_bkpf from bsak where bukrs = i_bkpf-bukrs
<b>and augbl = i_bkpf-belnr and augdt = i_bkpf-budat</b>
all is OK but condition augbl = i_bkpf-belnr and augdt = i_bkpf-budat has very poor performance!!
How to solve it? Do you have any solution?
Thank you very much.

Hi Vidlak,
If you might have noticed, BSAK has a secondary index available (number 1) with the fields :
LIFNR
BUKRS
AUGDT
AUGBL
GJAHR
BELNR
BUZEI
in the same order. Now since you cant obviously build and query on the primary key atleast try to complete the secondary index key. I can see i_bkpf has BUKRS & GJAHR key, and in the index AUGDT comes before AUGBL hence in construct your where clause for the third statement as
WHERE BUKRS EQ I_BKPF-BUKRS AND
             AUGDT EQ I_BKPF-BUDAT AND
AUGBL EQ I_BKPF-BELNR AND
GJAHR EQ I_BKPF-GJAHR.
this should certainly help improve performance.
Also seeing how many FOR ALL ENTRIES clauses u are using, one thing for performance improvement is ensure the table is NOT empty before using it and sort the table with its keys.
Hope its of some help.
