Performance issue in ECC 6.0, pls help!

Former Member — Wed, 26 Mar 2008 19:09:30 GMT

Dear all,

I have a join statement which works fine with the same data in 4.6 C but in the upgraded system it is too slow.

SELECT PA0105_{USRID PA0001}BUKRS PA0001~GSBER

INTO TABLE I_pa0001

FROM PA0105 INNER JOIN PA0001 ON PA0001_{PERNR = PA0105}PERNR

FOR ALL ENTRIES IN i_apqi

WHERE PA0001~ENDDA EQ '99991231'

AND PA0001~BUKRS IN S_bukrs

AND PA0001~GSBER IN S_GSBER

AND PA0105~SUBTY EQ '0001'

and pa0105~usrid = i_apqi-creator

AND PA0105~ENDDA EQ '99991231'.

Table i_apqi has a list of user ids. This is taking around 6 minutes which is too much. Any ideas to improve this?

Will be happy to reward points for the answers

Regards

Veena

Please optimize your internal table and delete the duplicate datas.

Hi,

First check whther the driver table i_apqi is empty or not by using if i_apqi[] is not initial.

Delete all the duplicate creator & sort it before making this select.

Try to use more where conditon, spl some key field

This query is having join + For all entries.

Try having all keys(primary) used in join condition. Before using FOR ALL ENTRIES IN i_apqi, try having sort table based on i_apqi-creator and delete adjacent duplicates comparing i_apqi-creator. I hope you are putting a check If not i_apqi[] is initial.

Also try using as many keys as possible in where conditions, this will help using all indexes available in data fetching process.

Hope this helps..

Hi,

I think you could use this code.

IF i_apqi[] IS NOT INITIAL.
SELECT PA0105~USRID PA0001~BUKRS PA0001~GSBER
INTO TABLE I_pa0001
FROM PA0105 INNER JOIN PA0001 ON PA0001~PERNR = PA0105~PERNR
FOR ALL ENTRIES IN i_apqi
WHERE pa0105~usrid = i_apqi-creator
AND PA0001~ENDDA EQ '99991231'
AND PA0001~BUKRS IN S_bukrs
AND PA0001~GSBER IN S_GSBER
AND PA0105~SUBTY EQ '0001'
AND PA0105~ENDDA EQ '99991231'
%_HINTS ORACLE 'FIRST_ROWS'.
ENDIF.

But your table i_apqi must have than first row creator
