Performance mach table

Moved to correct forum by moderator
Hi to everybody
Sorry for my simple question.
I'm programming with abap to few time
I would kown if is more fast/performance use:
loop at itab1.
loop at itab2 where......
endloop.
endloop.
or
loop at itab1
read table itab2- WITH KEY binary search.
endloop.
I ask this because I created a program and I must run in background otherwise it goes in dump time out.
Thanks e good work

Performance for table BKFP

Hi,
I would like to enquire is there anyway that i can improve the performance for table BKPF from the ABAP code point of view.
Because we have customise one program to generate report for the asset master listing.
one of the select statement are show as below:
 SELECT SINGLE * FROM BKPF WHERE BUKRS = ANEP-BUKRS
 AND GJAHR = ANEP-GJAHR
 AND AWKEY = AWKEYUS.
I would like to know how it different from the select statemene below:
SELECT SINGLE * FROM BKPF INTO CORRESPONDING FIELDS OF T_BKPF
 WHERE
 BUKRS = ANEP-BUKRS
AND GJAHR = ANEP-GJAHR
AND AWKEY = AWKEY.
Which of the select statements above can enhance report,because currently we have face quite bad issue on this report.
Can i post the ABAP code on this forum.
Hope someone can help me on this. thank you.

Hi,
As much as possible use the primary keys of BKPF which is BUKRS, BELNR and GJAHR. Also, select only the records which are needed so to increase performance. Please look at the code below:
DATA: lv_age_of_rec TYPE p.
FIELD-SYMBOLS: <fs_final> LIKE LINE OF it_final.
LOOP AT it_final ASSIGNING <fs_final>.
get records from BKPF
 SELECT SINGLE bukrs belnr gjahr budat bldat xblnr bktxt FROM bkpf
 INTO (bkpf-bukrs, bkpf-belnr, bkpf-gjahr, <fs_final>-budat,
 <fs_final>-bldat, <fs_final>-xblnr, <fs_final>-bktxt)
 WHERE bukrs = <fs_final>-bukrs
 AND belnr = <fs_final>-belnr
 AND gjahr = <fs_final>-gjahr.
if <fs_final>-shkzg = 'H', multiply dmbtr(amount in local currency)
by negative 1
 IF <fs_final>-shkzg = 'H'.
 <fs_final>-dmbtr = <fs_final>-dmbtr * -1.
 ENDIF.
combine company code(bukrs), accounting document number(belnr),
fiscal year(gjahr) and line item(buzei) to get long text.

How to define perform with table statement in ECC6.0

Hi all,
I am working on ECC6.0 version. I m using a perform to populate an internal table like this:-
 PERFORM explode TABLES li_zmpsdtl
 USING gs_matnr.
& its forms is defined as: -
FORM treat_one_item TABLES li_zmpsdtl STRUCTURE zmpsdtl
 USING gs_matnr TYPE matnr.
doing some action..............
endform.
While performing SLIN it shows an error message :-
" The current ABAP command is obsolete.
Within classes and interfaces, you can only use "TYPE" to refer to ABAP Dictionary types (not "LIKE" or "STRUCTURE"). "
If i use type in place of STRUCTURE then it is ok, but zmpsdtl should be defined as table type. :-
FORM treat_one_item TABLES li_zmpsdtl type zmpsdtl
 USING gs_matnr TYPE matnr.
doing some action..............
endform.
is there any other option to do the same thing. i dont want to create any teable type.
Thanx in advance,
Sachin

You have to use a global structure instead of a ddic structure after the STRUCTURE statement:
DATA: gs_zmpsdtl TYPE zmpsdtl.
FORM treat_one_item TABLES li_zmpsdtl STRUCTURE gs_zmpsdt
USING gs_matnr TYPE matnr.

How to improve Oracle Veridata Compair pair performance with tables that have big (30-40MB)CLOB/BLOB fileds ?

Can you use insert .. returning .. so you do not have to select the empty_clob back out.
[I have a similar problem but I do not know the primary key to select on, I am really looking for an atomic insert and fill clob mechanism, somone said you can create a clob fill it and use that in the insert, but I have not seen an example yet.]

DML operations performance on table indexed with CTXCAT

Hi,
I have a table with 2M records. The table is batch updated once a day, and the number of record movements (update/delete/insert) should be around 100K.
The table is indexed with CTXCAT.
If I create the index from scratch, it takes 5minutes.
If I perform delete/insert/update operations involving 40K records, it takes a lot more (especially for delete and update operations, something like 30 minutes).
In this particular case I can drop the index and recreate it from scratch every night. The problem is that the 2M records table is only the first step in adoption of Oracle Text. The next step will be a 40M records table, on which the initial index creation takes something like 2hours (so I can't rebuild it every night).
Do you have any suggest?
Thanks.

Hi kevinUCB,
I've decided to use CTXCAT indexes because I had to perform queries involving different columns (company name, city, region, etc.). So I thought CTXCAT was the right index for me.
Now I've discovered that if I index an XML with CONTEXT, I can perform a search on single XML fields, so CONTEXT is suitable for my needs.
Preliminary test on the 2M record table looks very good.
Bye,
Andrea

Problems with Performance in table AUSP - R/3

Hello, I am working with the set of tables (Klah, KSSK, KSML, AUSP, CABN in SAP R3) and generate reports with Crystal Reports 2008. The problem arises when displaying the data in Table AUSP, since the characteristics (Attin) are listed as records and I must show them grouped by the field AUSP.OBJEK as columns (see how in the transaction CL30N).
I probe with infoset, query / infoset and related tables in Crystal Reports but the performance is very bad.
Anybody know of a function standard similar to CL30N or I have only programmed in ABAP?
Edited by: Carolina Jerez on Oct 7, 2009 10:01 AM

Hi Ruven,
so you are able to log on to the portal from Windows via SSO. When you access the backend from the portal it is not working, right?
What kind of iView are you using to access the backend? Can you try with a simple Windows-SAPGui-iView? Is it working then? If you are using some web-based application to access the backend there might be a problem with different domains so that the SAPLogon Ticket is not passed along (both the URL of the portal and the URL of the backend have to be in the same domain -- of course there are way to enable SSO to different domains, but let's start with this simple case)
I would still recomend to use the Note mentioned above to trace what is actually sent to the backend (I don't think that the dataSourceConfiguration file you are using has anything to do with SSO not working from the portal to the backend).
Regards,
Holger.

CCM performance problems table info needed!!

Hello,
We have iimpemented SRM50 wit hCCM 200_700 level 6. We have serious performance problems when uploading content and publishing the catalogs. Does anybody know, as we have 29 procurement catalogs, if for all catalogs the entres are entered in the table /CCM/D_ITM.
We have 29 catalogs but only 4000 items so we think the entries are double. How many items and catalogs should CCM be able to handle ?
Thanks of course i will reward points

Performance ME51 table EBKN partially active

Hello group,
we suddenly had a performance issue, and we found that suddenly table EBKN appeared as "patially active" in the database. After activating the performance problems were gone. But we have no clue as to how the table got the status "partially active" and what this means. We got no errors or warnings when activating.
Doe sanyone have a clue as to what the cause is for the status "partially active"?
Regards, Léon Hoeneveld

Hi,
> I've checked with SE01 Transport organizer if any transport contained table EBKN.
it's not necessarily the table but could be one of the includes .... .
Partially active means that a part of the table (e.g. an include) was not active while the table (the part without the include) was active. You can try to find that part and search that in transports.
In the cases i had i was like this.
Regaring your performance problems: I wonder if they have to do with a partially activated table. Honestly i doubt it.
Programs working on partially activated tables should either work or dump but i never heard of performance problems
related to partially activated tables....
Kind regards,
Hermann

Can anybody help me with locating the tables, under what username should we look for them and
also if any special packs need to be installed for them.

Poor performances on tables FAGL_011ZC, FAGL_011PC and FAGL_011VC

We note from some time on a very very poor performances of some programme accessing these tables.
The tables are very small, still standard.
We see these tables does not have particular indexes, and their buffering is "allowed but disabled".
In you opinion can we activate the buffering of these tables ? Are there controindications ?
Our system is ECC5 quite aligned as SP level.

Can numbers perform pivot tables

can you create pivot tables on numbers the same way you can with excel?

No no pivot tables in numbers.... however...
Pivot tables are generally a fast method of using functions already existing to perform summarization, therefore even though they do not exist as an automatic function in numbers, you can use the basic CountIF, SumIF, etc... functions in a table you make to perform the same functionality. This has been done by many of us over the years and it works fairly well. You lose some of the "pivot" ability and no drag and drop. so it takes a little more planning beforehand.

Update Query is Performing Full table Scan of 1 Millions Records

Hello Everyboby I have one update query ,
UPDATE tablea SET
 task_status = 12
 WHERE tablea.link_id >0
 AND tablea.task_status <> 0
 AND tablea.event_class='eventexception'
 AND Exists(SELECT 1 from tablea ltask where ltask.task_id=tablea.link_id
 AND ltask.task_status = 0)
When I do explain plan it shows following result...
Execution Plan
0 UPDATE STATEMENT Optimizer=CHOOSE
1 0 UPDATE OF 'tablea'
2 1 FILTER
3 2 TABLE ACCESS (FULL) OF 'tablea'
4 2 TABLE ACCESS (BY INDEX ROWID) OF 'tablea'
5 4 INDEX (UNIQUE SCAN) OF 'PK_tablea' (UNIQUE)
NOW tablea may have more than 10 MILLION Records....This would take hell of time even if it has to
update 2 records....please suggest me some optimal solutions.....
Regards
Mahesh

I see your point but my question or logic say i have index on all columns used in where clauses so i find no reason for oracle to do full table scan,,,,
UPDATE tablea SET
task_status = 12
WHERE tablea.link_id >0
AND tablea.task_status <> 0
AND tablea.event_class='eventexception'
AND Exists(SELECT 1 from tablea ltask where ltask.task_id=tablea.link_id
AND ltask.task_status = 0)
I am clearly statis where task_status <> 0 and event_class= something and tablea.link_id >0
so ideal case FOR optimizer should be
Step 1)Select all the rowid having this condition...
Step 2)
For each row in rowid get all the row where task_status=0
and where taskid=linkid of rowid selected above...
Step 3)While looping for each rowid if it find any condition try for rowid obtained from ltask in task 2 update that record....
I want to have this kind of plan,,,,,does anyone know how to make oracle obtained this kind of plan......
It is try FULL TABLE SCAN is harmfull alteast not better than index scan.....

SQL performance - multiple tables or one bigger one?

One product will have 5 different types of media that need to
be
associated with it.
Some products will have, perhaps many items in one column
while none in
other columns
For Example
Product ID | ###
images | photoID1, PhotoID2
multimedia |
testimonials |
Pdfs | pdfid1
INserts | insertid1, insertid2 insertid3
Anyways, I am wondering if creating one table with multiple
columns is
better than many tables with just one of each of these
categories?
In other words, would it be better to have a table for
multi-media, a
table for pdfs and so on or one table for all of them. Some
rows will be
empty.
does the server take a bigger hit accessing multiple tables
win
individual items or one table with more columns that are,
perhaps empty?

That would be one possible way.

Don't do that, at least not in the way you described above.
But you
could do it with a single table if you would add a column
that describes
the media type:
productId
mediaType
mediaId
There would be a record for every single associated media. A
product
with 3 PDFs and 5 images would have 8 records in the media
table.
