Error at import abap in SAP NW installation
Hello all,
I am trying to install sap netweaver 7.02 AS ABAP 64 bit developer version for windows..
During installation at running phase 16 of 24 i.e IMPORT ABAP, i am getting the following error,
An error occurred while processing option SAP NetWeaver 7.0 including Enhancement Package 2 > SAP Application Server ABAP > MaxDB > Central System > Central System( Last error reported by the step :System call failed.

Hello Mahipal,
for me there is something visible. Please contact SAP to get access to the software. Maybe you do not have a license for this software ... or you are using the wron S-User.

Bad performance with inner join
Hi,
I have the following SQL-statement with a very bad performance:
SELECT
T_00 ."ERSDA" , T_00 . "AUFNR" , T_00 . "VORNR" , T_00 . "PERNR" ,
T_00 . "RUECK" , T_00 . "AUERU" , T_00 . "STOKZ" , T_00 . "STZHL" ,
T_00 . "ILE01" , T_00 . "ILE03" , T_00 ."ISBD" , T_00 . "ISBZ" ,
T_00 . "IEBD" , T_00 . "IEBZ" , T_00 ."SATZA" , T_00 . "LTXA1" ,
T_00 . "ERNAM" , T_00 . "WERKS" , T_00 ."GMNGA" , T_00 . "ISM01" ,
T_00 . "ISM02" , T_00 . "ISM03" , T_00 ."XMNGA" , T_01 . "ARBPL" ,
T_01 . "AUFNR" , T_01 . "VORNR"
FROM
"AFRU" T_00 INNER JOIN "S022" T_01 ON T_01 . "MANDT" = ? AND T_01 . "AUFNR" =T_00 . "AUFNR"
AND T_01 . "VORNR" = T_00. "VORNR"
WHERE
T_00 . "MANDT" = ? AND T_00 . "WERKS" =? AND T_00 . "ERSDA" = ? AND T_00 ."PERNR" = ?
The indices are:
AFRU~Z01: MANDT, PERNR, BUDAT
AFRU~Z02: MANDT, WERKS, ERSDA, PERNR
S022~A: MANDT, SSOUR, VRSIO, WERKS, ARBPL, KAPAR, MATNR, AUFNR, PLNUM, POSNR, PLNFL, VORNR
It seems, that the indices will not be used.
Have you got an idea, how can I improve the performance from this statement? With a new index, or can I rebuild the statement to archive a better performance. It is very urgent.
Thank you very much for you answers.
Regards,
Stefan G.

Re: Bad performance with inner join
Hi Stefan
You can try and do an re-org of the table and index and see if this will help
http://help.sap.com/saphelp_nw04/helpdata/en/1b/4e8f0d38a8f4419436d608a36b6581/frameset.htm
or you can have an look at the execution plan for the query and see where the most overhead and optimizer from there.

Re: Bad performance with inner join
Hello Stefan,
could you please send the explain plan executed via DatabaseStudio or SQlStudio as follows
or directly in St05.
I would expect that the join will be executed via select on the table AFRU using the index AFRU~Z02
and then accesses the second table S022.
Please send additionally the parameter values of te SQL statement. MaxDb is using a cost based optimizer which always sued the best strategies depending on the values in the where condition.
Which database version are you using?
You will find useful information about performance Analysis in our training about SQL Optimizer and in our Performacne guide section in SDN:
http://maxdb.sap.com/training/ session 16 Part 1 and for join part 2
and

Re: Bad performance with inner join
Hi Marius,
our database is MaxDB, not Oracle.
The execution plan shows me, that the most expensive statement is the inner join statement above.
Thank you for you help.

Re: Bad performance with inner join
Hello Stefan,
please check my last answer and post the required info please.
The explain output is the important one to check if the optimizer is executing the Inner join correctly.
Thanks,

Re: Bad performance with inner join
Hello Stefan,
ok now it is clear. The second statement has an equal condition on ERSDA -> so the index AFRU~z02 can be used and this execution is fast.
The first statement has an between condition on ERSDA - MaxDb cannot use the complete index AFRU~z02. The optimizer can use only these columns to the between - means of index AFRU~Z02 columes MANDT,WERKS,ERSDA but not the PERSNR anymore. So the optimizer evaluates if the aacess via another index can be used and evaluates index AFRU~Z01 -> here optimizer uses columes Mandt and PERSNR - looks like the PERSNR reducs the number of rows to be read more then reading index AFRU~z02
How to optimize this statement:
Create an 3. index AFRU~Z03 via the columes PERNR,WERKS,ERSDA
The explain must be as follows
AFRU~Z03 using columns PERSNR,WERKS,ERSDA then accessing the table S022
MANDT must not be part of this index because mandt is always the first key column and MaxDb uses the key columns as seperator in the index - so you always have the key column in the index as well. ( maxDb ios not working qwith rowids). Ok PERSNR seems to be the column with the most distince values (my experieice) put it as the first index column. Werks is the second equal condition in the stamtement - so put it as second index column, and at last the column with the between condition.
This is the reason why I recommend to create the index with PERSNR,WERKS,ERSDA
The explain will look as follows:
AFRU~Z03
PERSNR
WERKS
ERSDA
MANDT ( use key column)
join via key range to S022 but only using column MANDT.
Ok to optimize the join transition for both statements we have to have a closer look on the join conditions.
Mandt =
AUFNR =
VORNR =
There seems to be no index on S022 with the columns AUFNR,VORNR
Mandt don't need to be part of the index as well.
So please create both indexes as described in my answer - and I'm interesting in the result ..... could the runtime of both statements be speed up?
