HI All,
I have written a Select Query for a BW Datasource. The query seems to work fine when the data is less e.g. in Dev system, but when we move to QA it times out because of the Volume of data.
The join is on 5 different tables. Any pointers to optimise the query would helpful
At the moment query is something like
select
t1~objid
t2~objid as objid_m
t2~smlevycat
t3~objid as objid_se
t3~seccat1
t4~begda
t4~peryr
t4~perid
t5~knumh
t5~kschl
t6~kbetr
t6~konwa
* into
* table t_cprice
from hrp1001 as t1
inner join hrp1742 as t2 on t2~objid = t1~sobid and t1~mandt = t2~mandt
inner join hrp1743 as t3 on t3~objid = t1~objid and t3~mandt = t1~mandt
inner join hrp1739 as t4 on t4~objid = t1~objid and t4~mandt = t1~mandt and t4~mandt = t3~mandt
inner join a913 as t5 on t5~kschl = t2~smlevycat and t5~cmsmsecat1 = t3~seccat1 and t5~mandt = t2~mandt and t5~mandt = t3~mandt and t5~cmperid = t4~perid and t5~cmperyr = t4~peryr
inner join konp as t6 on t6~knumh = t5~knumh and t6~mandt = t5~mandt and t6~kschl = t2~smlevycat
where
t1~otype = 'SE' and
t1~sclas = 'SM' and
t1~plvar = '01' and
t2~otype = 'SM' and
t2~plvar = '01' and
t3~otype = 'SE' and
t3~plvar = '01' and
t4~plvar = '01' and
t4~otype = 'SE' and
t5~kappl = 'CM' and
t1~objid in l_r_epid and
t2~objid in l_r_modid and
t2~smlevycat in l_r_scat and
t3~seccat1 in l_r_sect1 and
t4~begda in l_r_begda and
t4~peryr in l_r_ayear and
t4~perid in l_r_asess and
t5~datbi ge sy-datum and "Validity End Date
t5~datab le sy-datum. "Validity Start Date
Thanks,
