report performance

Former Member — Wed, 28 Feb 2007 17:40:46 GMT

I have a report program which is taking a lot of time in test system . I ran it in dev system it was ok . There are more records in test and its taking a lot of time . I tried my best to improve its performance . I appreciate if anyone can help me in improving its performance.

I didn't go through your entire code but this statement in the loop of ZCOSTHIST stopped me.

SELECT KNUMH DATAB FROM A118 INTO TABLE IT_A118 WHERE KAPPL = 'V'

AND KSCHL = 'PR00'

AND MATNR = IT_ZCOSTHIST-MATNR

ORDER BY DATAB DESCENDING.

It's always not safe to write selects in the loop since it goes to the database for each loop pass and tries to get the record. Rather do a select from A118 for all entries of ZCOSTHIST and play with your internal tables. Make this correction and check it to see if there is any improvement. then we can go with the other steps.

you can write your select like this outside the loop and in the loop you can read the statement or loop it again if necessary based on your requirement.

SELECT KNUMH

DATAB

FROM A118

for all entries of IT_ZCOSTHIST

INTO TABLE IT_A118

WHERE KAPPL = 'V'

AND KSCHL = 'PR00'

AND MATNR = IT_ZCOSTHIST-MATNR

ORDER BY DATAB DESCENDING.

Re: report performance

good

you can try the TCODE SLIN,which ll give you detail errors where you need to be change to increase the performance of the program.

Hey Deepthi,

You Should NEVER use SELECT statements inside the LOOP. This puts great impact on the performance.

At the End of the code when FOUND = 1, Please see if you can remove those SELECT statements also from the LOOP as i am not sure hat exactl the requirement is?

and ALWAYS use 'EQ' instead of '=' as i told u before.

DECLARE CONSTANTS wherever u used then in your coding.It shows the good coding practise and will be easy for other who go thru you's code.

ALWAYS check IF ITAB has entries before using FOR ALL ENTRIES otherwise it will pick al the data from the database and canresult in SHORT DUMP.

hope this will help.

Thanks n Regards,

Ashwani

Re: report performance

Former Member — Wed, 28 Feb 2007 20:04:03 GMT

I am getting an error at this select statement. object id length is 90 and it_cond-knumh length is 10 . the error is because of the different lengths .

IF NOT IT_COND[] IS INITIAL.

SELECT USERNAME UDATE UTIME FROM CDHDR INTO TABLE IT_CDHDR FOR ALL ENTRIES IN IT_COND WHERE OBJECTCLAS = 'COND_A' AND OBJECTID = IT_COND-KNUMH.

ENDIF.

Re: report performance

Former Member — Wed, 28 Feb 2007 20:05:50 GMT

Hello Deepthi,

U can make use of the FM READ_HEADER_CHANGES to read data from the CDHDR Table. It will faster also.

If useful reward.

Re: report performance

Former Member — Wed, 28 Feb 2007 20:07:02 GMT

SELECT USERNAME UDATE UTIME FROM CDHDR INTO TABLE IT_CDHDR FOR ALL ENTRIES IN IT_COND WHERE OBJECTCLAS EQ 'COND_A' AND OBJECTID+0(10) EQ IT_COND-KNUMH.

ALWAYS use 'EQ' as i ave used in the above query for permonace.

Try uing it f dat works. i m not on the system so can't test it.

I tried it in every possible way , +(10) is not working for this statement at all . i am trying to use the FM ,i see it as CHANGEDOCUMENT_READ_HEADERS. If i am using a set of object ids (i have it in it_cond) , how do i call the function module in a loop.

Re: report performance

Former Member — Wed, 28 Feb 2007 20:35:50 GMT

Yes U need to call the FM in the LOOP AT IT_COND

Vasanth

Re: report performance

Former Member — Wed, 28 Feb 2007 20:44:44 GMT

if you are sure of the length that its going to be 10 then declare the it_cond-knumh as 10 type c.

Is your problem solved or else try the above ?

Re: report performance

Former Member — Wed, 28 Feb 2007 20:55:19 GMT

The performance has become even more worse now.

SELECT KNUMH

DATAB

FROM A005

INTO TABLE IT_A005

FOR ALL ENTRIES IN IT_ZCOSTHIST

WHERE KAPPL = 'V'

AND KSCHL = 'PR00'

AND MATNR = IT_ZCOSTHIST-MATNR.

SORT IT_A005 BY MATNR ASCENDING DATAB DESCENDING.

DELETE ADJACENT DUPLICATES FROM IT_A005 COMPARING MATNR.

A005 is a pooled table . How do i change this statement to improve the performance. The control is not coming out of this statement

Re: report performance

Former Member — Wed, 28 Feb 2007 21:00:18 GMT

Is ur problem of different lenghts solved?

plz. chech the field status in table A005.

which comes after which ... order the fields in WHERE clause in the same manner as they are in Table A005.

hope this will help

Thanks

your fields in the select should be in the order of the database table and also the fields in the where class also before all this the internal table it_ZCOSTHIST should be sorted for better performance.

I am sure writing a select outside the loop is much much better. It should improve. check it with these modifications too.
