Hi,
Let me understand your code first.
The below code (the 2 selects) gets data from BSEG first and then gets data from BKPF table.
"*Selecting the Document number from BSEG table
SELECT BELNR BUKRS FROM BSEG INTO TABLE L_DOC_NO
WHERE BUKRS IN S_BUKRS
AND GJAHR = P_GJAHR
AND HKONT IN S_SAKNR.
IF SY-SUBRC 0.
MESSAGE ID 'ZTFI' TYPE 'E' NUMBER 006.
ENDIF.
CLEAR L_DOC_NO.
SORT L_DOC_NO BY BELNR.
"*Selecting the Document Number Based on the selection-screen.
SELECT BELNR BUKRS BUDAT CPUDT BLART MONAT FROM BKPF INTO TABLE L_BKPF
FOR ALL ENTRIES IN L_DOC_NO
WHERE BUKRS = L_DOC_NO-BUKRS AND
BELNR = L_DOC_NO-BELNR AND
GJAHR = P_GJAHR AND
BUDAT IN S_BUDAT AND
MONAT IN S_MONAT.
IF SY-SUBRC 0.
MESSAGE ID 'ZTFI' TYPE 'E' NUMBER 006.
ENDIF.
The below code, can't you avoid by taking all the fields required on your 1st select on BSEG table?
*Fetch the Line Items
SORT L_BKPF BY BELNR.
SELECT BELNR BUKRS BUZEI HKONT SHKZG WRBTR FROM BSEG INTO TABLE

AND BELNR = L_BKPF-BELNR
AND GJAHR = P_GJAHR
AND BUZEI BETWEEN '001' AND '999'.
Please check the below blog on "Performance of Nested Loops" by Rob Burbank which would be really helpful.

Regarding performance optimization and tuning...

hi all,
<b>please provide me the performance tuning scenarios and parameters of an R/3 system with Oracle..</b>
i heartly welcome all docs and pdf links or notes related to this issue..
please provide ur suggestions at the earliest...
expecting ur response..
<i>Vineeth</i>

Hello,
there are many SAP Notes regarding performance issues. Here are just a couple of them:
618868
805934
793113
805934
Please also have a look at the lists of the relating Notes at the end of each Note.
But still much more effective would be to read the book of
<a href="http://www.sap-press.de/katalog/buecher/titel/gp/titelID-1155?GalileoSession=66220888A2.lRCIISlE">T.Schneider Performance Optimization Guide</a>.
It's the best performance tuning guide. The course ADM315 (or BC315?) ist also very helpful.

Regarding Indexes and performance tuning.

Hi Everyone,
I need some elaborate explanation about indexes and performance tuning.
1. How do you find out whether the select query which I write is utilizing the indexes .
2. Is it true that the sequence in which the indexes are defined in se11
for eg: MANDT
KNUMH
KOPOS
your select query should also have the same sequence in the where clause else the indexes are not utilized well .
3. Is there any precautions/ special method to write select queries for proper utilization of indexes.
Thanks to all reading and answering in advance.
Rgds,
Anu.

Hi
You will find like this
If your select like this
select matnr mtart from mara into<itab>
where matnr = <>..
Go to table and see mara ..if matnr is checked as primary key,then you are using primary index.
Check secondary index tab and see if any fields,if those fields you are using in select then you are using secondary index.
2.Not sequence,check how many fields are checked tick as primary key,all thsoe are index.
3.Always try to use proper primary index in select statment and avoid nested select statements.
Thanks

Report running for long time & performance tuning

Hi All,
(1). WebI report is running for long time.so what are the steps i need to check for it ?
(2). Can you tell me about performance tuning in BO ?
please help me.....
Thanks
Kumar

(1). WebI report is running for long time.so what are the steps i need to check for it ?
The first step is to see if the problem lies in the query on the data source or in webi itself. Depending on the data source there are different ways to extract the query and try to run it against the database. Which source does your report uses?
(2). Can you tell me about performance tuning in BO ?
I would recommend to start by reading the administrator's guide. There is a section about how to improve performance.

Stratos

Oracle 11g Performance tuning approach ?

Hello Experts,
Is it the right forum to follow oracle performance tuning discussions ? If not, let me know what will be the forum to pick up some thread on this subject.
I am looking for performance tuning approach for oracle 11g. I learned there are some new items in 11g in this regard. For persons, who did tuning in earlier versions of Oracle,
what will be the best way adopt to 11 g?
I reviewed the 11g performance tuning guide, but I am looking for some white papers/blogs with case studies and practical approaches. I hope that you have used them.
What are the other sources to pick up some discussions?
Do you mind, share your thoughts?
Thanks in advance.

Performance tuning in XI, (SAP Note 857530 )

Could any one pls tell me where to find sap notes.
I am looking for "SAP Note 857530 "
Integration process performance(in sap XI).
or how can I view the performance of the integration process ? or exactly how performance tuning is done.
pls help,
Best regards,

Solution
This note refers to all notes that are concerned with improving the performance of the ccBPM runtime.
This note will be continually updated as improvements are made.
Also read the document "Checklist: Making Correct Use of Integration Processes" in the SAP Library documentation, on SAP Service Marketplace, and in SDN; it contains information about performance issues to bear in mind when you model integration processes.
Refer to the appended notes and maintain the default code changes by using SNOTE, or by importing the relevant service packs. Note that some performance improvements cannot be implemented by using SNOTE and are instead only available in service packs.

Performance tuning in EP6 SP14

Hi,
We just migrated our development EP5 SP6 portal to NW04 EP6 SP14 and are seeing some performance problems with a limited number of users (about 3).
Please point me to some good clear documentation related to performance tuning. Better yet, please tell me some things you have done in your EP6 portal to improve performance.
Any help is greatly appreciated.
Regards,
Rick

Hi
In general we have experienced that NW04 is faster than earlier versions.
One of the big questions is if the response time is SERVER time (used for processing on the J2EE server), NETWORK time (latency and many roundtrips), CLIENT time (rendering, virus-scanning etc) or a combination.
1) Is the capacity on the server ok? CPU utilization and queue lenght high? Memory swapping?
2) A quick optimazation server-side is logging: Plese verify that that log and trace levels are ERROR /FATAL or NONE on J2EE and also avoid logging on IIS and IIS proxy is used
3) Using a HTTP trace you can see if the NW portal for some reason generetes more roundtrips (more GETS) that the old portal for the same content - what is the network latency? Try to do a "ping <server>" from a client pc and see the time (latency) - if it is below 20 ms the network should do a big difference.
4) On the client try to call the portal with anti-virus de-activated if the delta/difference in response times are HUGE your client could be to old? (don't underestimate the client). Maybee the compression should be set different to avoid compres (server) and uncompres (client) - this is a tradeoff with network latency however.
Also client-side caching (in browser) is important.
These are just QUICK point to consider - tuning is complex

Performance Tuning in IR

Hello All,
We have created some reports using Interactive Reporting Studio. The volume of data in that Oracle database are huge and in some tables of the relational database are having above 3-4 crores rows individually. We have created the .oce connection file using the 'Oracle Net' option. Oracle client ver is 10g. We earlier created pivot, chart and report in those .bqy files but had to delete those where-ever possible to decrease the processing time for getting those report generated.
But deleting those from the file and retaining just the result section (the bare minimum part of the file) even not yet helped us out solving the performance issue fully. Still now, in some reports, system gives error message 'Out of Memory' at the time of processing those reports. The memory of the client PCs,wherefrom the reports are being generated are 1 - 1.5 GB. For some reports, even it takes 1-2 hours for saving the results after process. In some cases, the PCs gets hanged at the time of processing. When we extract the query of those reports in sql and run them in TOAD/SQL PLUS, they take not so much time like IR.
Would you please help us out in the aforesaid issue ASAP? Please share your views/tips/suggestions etc in respect of performance tuning for IR. All reply would be highly appreciated.
Regards,
Raj

SQL + & Toad are tools that send SQL and spool results; IR is a tool that sends a request to the database to run SQL and then fiddles with the results before the user is even told data has been received. You need to minimize the time spent by IR manipulating results into objects the user isn't even asking for.
When a request is made to the database, Hyperion will wait until all of the results have been received. Once ALL of the results have been received, then IR will make multiple passes to apply sorts, filters and computed items existing in the results section. For some unknown reason, those three steps are performed more inefficiently then they would be performed in a table section. Only after all of the computed items have been calculated, all filters applied and all sorts sorted, then IR will start to calculate any reports, charts and pivots. After all that is done, the report stops processing and the data has been "returned"
To increase performance, you need to fine tune your IR Services and your BQY docs. Replicate your DAS on your server - it can only transfer 2g before it dies, restarts and your requested document hangs. You can replicated the DAS multiple times and should do so to make sure there are enough resources available for any concurrent users to make necessary requests and have data delivered to them.
To tune your bqy documents...
1) Your Results section MUST be free of any sorts, filters, or computed items. Create a staging table and put any sorts or local filters there. Move as many of your computed items to your database request line and ask the database to make the calculation (either directly or through stored procedures) so you are not at the mercy of the client machine. Any computed items that cannot be moved to the request line, need to be put on your new staging table.
2) Ask the users to choose filters. Programmatically build dynamic filters based on what the user is looking for. The goal is to cast a net only as big as the user needs so you are not bringing back unnecessary data. Otherwise, you will bring your server and client machines to a grinding halt.
3) Halt any report pagination. Built your reports from their own tables and put a dummy filter on the table that forces 0 rows in the table until the report is invoked. Hyperion will paginate every report BEFORE it even tells the user it has results so this will prevent the user from waiting an hour while 1000s of pages are paginated across multiple reports
4) Halt any object rendering until request. Same as above - create a system programmically for the user to tell the bqy what they want so they are not waiting forever for a pivot and 2 reports to compile and paginate when they want just a chart.
5) Saved compressed documents
6) Unless this document can be run as a job, there should be NO results stored with the document but if you do save results with the document, store the calculations too so you at least don't have to wait for them to pass again.
7) Remove all duplicate images and keep the image file size small.
Hope this helps!
PS: I forgot to mention - aside from results sections, in documents where the results are NOT saved, additional table sections take up very, very, very small bits of file size and, as long as there are not excessively larger images the same is true for Reports, Pivots and Charts. Additionally, the impact of file size only matters when the user is requesting the document. The file size is never an issue when the user is processing the report because it has already been delivered to them and cached (in workspace and in the web client)

Performance tuning in Query

Dear All,
My client wants to do the performance tuning in a query where it has the Global structure of 300 CKF & 300 RKF.
They dont want to touch the MP, all they want to do some performance tuning through the front end without touching the Multiprovider.
The CKF is little bit tricky where in Each CKF has 28 RKF and In each RKF atleast 2 variables are used an with hierarchy restrictions. The query is taking 30 - 40 min to execute. Kindly guide me how to handle this.
Regards,
Suman Thangadurai.

HI,
Improving query performance u2013
-     Generate index.
-     Build query on multiprovider and better use Constant Selection Function to bring infoset functionality to Multiprovider.
-     Make your query more dynamic using variables.
-     Do partitioning on IC when you have restriction on 0CALMONTH.
-     Use more free charecterstics.
-     Use include than exclude at Bex level.
-     Utilize Cache mode and Read mode functions.

Performance tuning in Smart form

Hi,
How to performance tuning in Smart form level
Any tips available kindly send me any one .
Thanks&Regards,
Maya

Hi,
If you are using a customized print program to call the Smart Form...it is better to fetch most of the data as much as possible within it and pass it useing form interface/functional module interface.
Then in the ABAP code where ever used, fallowing the ABAP coding performance tuning options like avoiding the MOVE-CORRESPONDING, INTO CORRESPONDING, using binary search for READ statement...etc...
