BSIS performance is very Slow in query

Dear All,

How to increase performance for the following query BSIS

select a~saknr as glcode

b~txt50 as gldesc

into corresponding fields of table it_final

from skb1 as a

inner join skat as b

on a_{saknr = b}saknr

where a~saknr in p_glcode

and a~bukrs eq company

and b~spras eq 'EN'

and b~ktopl eq 'ABIX'.

sort it_gl by saknr.

• the above query get 220 G/L accounts.*

if not it_final[] is initial.

select

bukrs

hkont

augdt

augbl

zuonr

gjahr

belnr

buzei

budat

werks

kostl

aufnr

shkzg

dmbtr

prctr

into corresponding fields of table it_bseg

from bsis

for all entries in it_final

where bukrs eq company

and prctr eq s_prctr

and gjahr eq s_year

and hkont eq it_final-glcode

and budat in s_budat "BETWEEN fromdt AND todt .
