Query Performace Issue-Usage of SAP_DROP_EMPTY_FPARTITIONS Program

Hi Experts,
We are facing query peroformance issue in our BW Production System. Queries on the Sales Multiprovider are taking lot of time to run. We need to tune the query perofrmace.
We need to drop the empty partitions at the database level. Have anyone of you used the program SAP_DROP_EMPTY_FPARTITIONS to drop the empty partitions ? If Yes, Please provide me with details of your experience of using this program. Please let me know, whether there are any disadvantages using this program in the Production System.
Kindly treat this as an urgent requirement.
Your help will be appreciated....
Thanks,
Shalaka

Hi Shwetha,
I think that pgm drops if partition contains no records(in DEL_CNT)
or if partitions requid is not in dimtab (DEL_DIM)
Hope it helps!
(and don't forget to reward the answer, if you want !)
Bye,
Roberto

Query Performance Issues

Hi Gurus,
I m woking on performance tuning at the moment and wants some tips
regarding the Query performance tuning,if anyone can helpme in that
rfrence.
the thing is that i have got an idea about the system and now the
issues r with DB space, Abap Dumps, problem in free space in table
space, no number range buffering,cubes r using too many aggrigates,
large IC,Large ODS, and many others.
So my questionis that is anyone can tell me that how to resolve the
issues with the Large master data tables,and large ODS,and one more
importnat issue is KPI´s exceding there refrence valuses so any idea
how to deal with them.
waiting for the valuable responces.
thanks In advance

Hi Amit
For Query performance issue u can go for :-
Aggregates : They will help u a lot to make ur query faster becuase query doesnt hits ur cube it hits the aggregates which has very less number of records in comp to ur cube
secondly i wud suggest u is use CKF in place of formulaes if any in the query
other thing is avoid upto the extent possible the use fo nav attr . if u want to use them use it upto the minimal level reason i am saying so is during the query exec whn ever there is nav attr it provides unncessary join to ur MD and thus dec query perfo
be specifc to rows and columns if u r not sure of a kf or a char then better put it in a free char.
use filters if possible
if u follow these m sure ur query perfo will inc
Assign points if applicable
Thanks

I worked on the query a month ago and the fix worked for me in test intance but failed in production. Following is the URL for the previous thread.

Either the statistics are not up to date, the data values are skewed or you have some optimizer parameter set to none default to force index access.
Please post explain plan and optimizer* parameter settings.

Schedule/Execute POWL Query in Background or via ABAP Program

Hi all,
I would like to know if there is any chance/possibilities to schedule/execute the POWL Query for example the Query ID
"SAPSSRM_R_CENTRALCONFIRM_01_01" Confirmations Pending in the background to output report.
Or perhaps there is anyway I can make use of the logic within the Query ID above in an ABAP program?
The main reason is that I need create a Confirmations Pending report and sent out to relevant SC Creator and the quickest way is to make use of the existing query of above.
Many thanks and regards,
Hon Leong

Hi Hon Leong,
please first check POWL - Web Dynpro ABAP - SCN Wiki to understand, how POWL works.
You need to find a Feeder Class of your query and execude GET_OBJECTS Method to get the result list.
For example you can check report POWL_WLOAD or function module POWL_QUERY_REFRESH.

Konstantin

What does it mean when the usecounts of Parse Tree for a view is incrementing when a select query is issued against the view?

I'm using SQL Server 2008 R2 (10.50.4033) and I'm troubleshooting an issue that a select query against a specific view is taking more than 30 seconds consistently.   The issue just starts happening this week and there is no mass changes in data.
The problem only occur if the query is issued from an IIS application but not from SSMS. One thing I noticed is that sys.dm_exec_cached_plans is returning 2 Parse Tree rows for the view - one created when the select query is issued
1st time from the IIS application and another one created when the same select query is issued 1st time from SSMS.   The usecounts of the Parse Tree row for the view (the IIS one) is increasing whenever the select query is issued.  The
usecounts of the Parse Tree row for the view (the SSMS one) does not increase when the select query is issued again.
There seems to be a correlation between the slowness of the query and the increasing of the usecounts of the Parse Tree row for the view.
I don't know why there is 2 Parse Tree rows for the view. There is also 2 Compiled Plan rows for the select query.
What does the Parse Tree row mean especially the usecounts column?

>> The issue just starts happening this week and there is no mass changes in data.
There might be a mass changes in the execution plan for several reason without mass changes in data
If you have the old version and a way to check the old execution plan, and compare to the new one, that this should be your starting point. In most cases you don't have this option and we need to monitor from scratch.
>> The problem only occur if the query is issued from an IIS application but not from SSMS.
This mean that we know exactly what is the different and you can compare both execution plan. once you do it, you will find that they are no the same. But this is very common issue and we can know that it is a result of different SETting while connecting
from different application. SSMS is an external app like any app that you develop in Visual studio but the SSMS dose not use the Dot.Net default options.
Please check this link, to find the full explanation and solutions:
http://www.sommarskog.se/query-plan-mysteries.html
Take a look at sys.dm_exec_sessions for your ASP.Net application and for your SSMS session.
If you need more specific help, then we need more information and less stories :-)
We need to see the DDL+DML+Query and both execution plans
>> What does the Parse Tree row mean
I am not sure what you mean but the parse tree represents the logical steps necessary to execute the query that has been requested. you can check this tutorial about the execution plan: https://www.simple-talk.com/sql/performance/execution-plan-basics/ or
this one: http://www.developer.com/db/understanding-a-sql-server-query-execution-plan.html
>> regarding the usecount column or any other column check this link:

Query Throttling issue after increasing List view threshold in connected webpart

Dear SharePointers,
I have connnected listview webpart deployed on site. Parent webpart
has 16 fields and over 3,000 listitems exists in list. Child webpart has 7 fields and more than 30,000 Items. The code works well in other sites in same web app and it also works well in other systems. We tested same in other system by increasing/decreasing
data but still we are not able to replicate issue. I know that this issue could also encounter if fields are not indexed in the list. Are there any other pointers which can use to debug this issue.

Excel tables for database usage in external programs such as game engines?

Hello!
Where can I find more information about using Excel tables for database usage in external programs such as game engines? Do I have to use SQL, CSV or XML?
Thank you!

Hi,
As far as I know, Excel is a good way to use as database file. Whether it is a personal list of phone numbers, a contact list for members of an organization or team, or a collection of coins, cards, or books, an Excel database file makes it easy to
enter, store, and find specific information.
You could choose Excel,SQL,Access, CSV or XML as database according to your goal.
Here are some articles to introduce "How to use Excel table as database":

Oracle 11g performace issue

hi all,
am using oracle 11g enterprise edition., i didn't ran any query but in ADDR report it was running some sytem based query(SYS,DBSNMP,SYSMAN etc)
but in previous 10g it was working fine.. can anyone tell me how to stop those query..
this is the query was running most frequently :
select end_time, wait_class#, (time_waited_fg)/(intsize_csec/100), (time_waited)/(intsize_csec/100), 0
from v$waitclassmetric union all
select fg.end_time, -1, fg.value, bg.value, dbtime.value

Do you really think these queries uses high resource and have high elapsed time then you custom queries? The god way to diagnose a performance problem is to identify most resource intensive/time consuming program/module/code rather then running after background queries. Yes sometimes background queries too run slowly in rear cases and then you need to run dbms_stats.gather_dictionary_stats or dbms_stats.gather_fixed_objects_stats (https://blogs.oracle.com/optimizer/entry/fixed_objects_statistics_and_why)

Oracle 11g on Linux : Query Optimization issue

Hi guru,
I am facing one query optimization related problem in group by query
Table (10 million Records)
Product(ProductId number,ProductName varchar(100),CategoryId VARCHAR2(38),SubCategoryId VARCHAR2(38))
Index
create index idxCategory on Product (CategoryId,SubCategoryId)
Query1:To find product count for all CategoryId and SubCategoryId
select CategoryId,SubCategoryId,count(*) from Product group by CategoryId,SubCategoryId
Above query is not using index idxCategory and doing table scan which is very costly.
When I fire Query2: select count(*) from Product group by CategoryId,SubCategoryId
then it is properly using index idxCategory and very fast.
Even I specified hint in Query1 but it is not using hint.
Can anybody suggest why oracle is not using index in Query1 and what should I do so that Query1 will use Index.
Thanks in advance.

Can anybody suggest why oracle is not using index in Query1 and what should I do so that Query1 will use Index.The most obvious reason that the table needs to be visited would be that the columns "CategoryId" / "SubCategoryId" can be NULL but then this should apply to both queries. You could try the following to check the NULL issue:
select CategoryId,SubCategoryId,count(*) from Product where CategoryId is not null and SubCategoryId is not null group by CategoryId,SubCategoryId
Does this query use the index?
Can you show us the hint you've used to force the index usage and the EXPLAIN PLAN output of the two queries including the "Predicate Information" section? Use DBMS_XPLAN.DISPLAY to get a proper output, and use the \ tag before and after when posting here to format it using fixed font. Use the "Quote" button in the message editor to see how I used the \ tag here.
Are above queries representing the actual queries used or did you omit some predicates etc. for simplicity?
By the way, VARCHAR2(38) and ...ID as name, are these columns storing number values?

Support pack level issue in Standard Finance Program.

Hi Everyone,
                i have an issue which is related to Finance. Actually, Finance People are Using a Standard Report (FS10N) - GL Account Line item display. There,Vendor and Customer Details are not displayed (Customer/Vedor Filed is empty) for the normal GL Account. But for the Reconsalation GL accounts they are able to see.
               For this issue SAP released an SNOTE 1107639 and correction delivered in SAP_APPL support pack 12.And we already applied it in the system and our current SAP_APPL level is 14. Though it is already available why the problem is still persist. Another thing is, for the same issue there is another SNOTE 1034354 which guides to enhancement thro' some BADI work in standard program.
              My question is that if the correction is available in a patch and that is imported as well in to system without any error then it should resolving the problem.but in this case why it does not work out or what could be the reason behind this. As a Basis admin i would like to know.
Thanks&Regards,
Siva

Hi Siva,
Your query is obsolutely acceptable...
After supportpack update some times database will not be synchronised with the new updates.
and more over it seems there is a complete issue with SAP side.... there is only one option in u r hand now just restart the system.but please make sure to take the down time...and check whether the correction is working or not..if not then no luck u need to contact SAP global team and ask them why the corrections are not working properly..

SAP Query format issue (with ABAP list)

Hi All,
I had a requirement to remove all unecessary formatting and text from a SAP query report which can be read by a third party software system. We need only Header line and report data (spaced by Tab).
I have removed all formatting from the report and changed the output format from "SAP list viewer" to "ABAP list" .
The issue is that the report shows material number with 12 digits in output but when we download to file then it adds extra six "0" and makes the Material Number field as 18 digit.
we have already maintained new length as 12 againts the standard length 18 for material number(under field output option)
Please suggest how to get rid of extra digits generated during downloading.
Please help,
Thanks,
Rohit

Hi Brad,
Currently we execute query with SQ01 and from the output screen the user direclty saves the file as "local file..."
The output format is "abap list". We are able to get the exact format but the only problem is with material number. I cant make changes in the program. Is there a way to download it without changing the 12 character ( as displayed on the report output)
Thanks for help.
Rohit

Query Variable Issue

Dear BI Experts, I have created a custom variable (single entry, optional) that looks similar to 0S_FPER. I am trying to use it with an offset -1 in 2 columns with Restricted key Figures (RKF's) and trying to save the query, I am getting "Terminate: System error in program SAPLRRII2 and form REP_ASSIGN_INITIAL_OPT-01" and I cannot save it.
Does anybody know how I can resolve it?

hi,
I have faced same issue some time back. This is due to GUI bug. You can definetly solve this by doing these steps
1. Goto C:\Program Files\SAP\FrontEnd\SAPGui, find the file wdbsPres.dll take a copy of this.
Now, goto OSS note 1039191, you should find a zip file by name Hotfix21032007.zip..
unzip you should find the new version of the file wdbsPres.dll.
Overwrite the file in C:\Program Files\SAP\FrontEnd\SAPGui with this new version available in the OSS note.
This will solve your issue.

Query Performance Issues on a cube sized 64GB.

Hi,
We have a non-time based cube whose size is 64 GB . Effectively, I can't use time dimension for partitioning. The transaction table has ~ 850 million records. We have 20+ dimensions among which 2 of the dimensions have 50 million records.
I have equally distributed the fact table records among 60 partitions. Each partition size is around 900 MB.
The processing of the cube is not an issue as it completes in 3.5 hours. The issue is with the query performance of the cube.
When an MDX query is submitted, unfortunately, in majority of the cases the storage engine has to scan all the partitions (as our cube is not time dependent and we can't find a suitable dimension that will fit the bill to partition measure group based
on it.)
I'm aware of the cache warming and usage based aggregation(UBO) techniques.
However, the cube is available for users to perform adhoc queries and hence the benefits of cache warming and UBO may cease to contribute to the performance gain as there is a high probability that each user may look at the data from different perspectives
(especially when we have 20 + dimensions) as day(s) progress.
Also, we have 15 + average calculations (calculated measures) in the cube. So, the storage engine sends all the granular data that the formula engine might have requested (could be millions of rows) and then perform the average calculation.
A look at the profiler suggested that considerable amount of time has been spent by storage engine to gather the records (from 60 partitions).
FYI - Our server has RAM 32 GB and 8 cores and it is exclusive to Analysis Services.
I would appreciate comments from anyone who has worked on a large cube that is not time dependent and the steps they took to improve the adhoc query performance for the users.
Thanks

Hello CoolP,
Here is a good articles regarding how to tuning query performance in SSAS, please see:
Analysis Services Query Performance Top 10 Best Practices:
http://technet.microsoft.com/en-us/library/cc966527.aspx
Hope you can find some helpful clues to tuning your SSAS Server query performance. Moreover, there are two ways to improve the query response time for an increasing number of end-users:
Adding more power to the existing server (scale up)
Distributing the load among several small servers (scale out)

SQL query / binding issues on my web page

This may or maynot be the place to ask, but maybe someone can
tell me what
to look at...
I created a page some time back.. and its displays a few
fields of data
based on the id passed to it..
This works fine, but now that we are trying to improve the
site a little,
they want some additonal information displayed
on the page.. so those changes were made about 2 weeks ago...
now that some
of the newer records contain the data
they want displayed, some data is not displaying.. or it will
display and
other fields ( that were displaying before ) are now
missing.. the web page hasnt been touched in 2 weeks.. if we
execute the
store procedure within SQL and within our web program
it always returns the correct data.. but the fields that i
have binded to
the page are taking on a life of there own...
Not sure if anyone has had this problem, but its getting
annoying.. when i
execute this within SQL it returns all the values requested.
If i execute it
within dreamweaver to show me what results i will get back it
works there..
but after i bind the fields to my page and view it only some
or all my
fields do not display any data... but if i play around with
the order of my
select statement below i can get some fields to display and
other
disappear... and i dont ever touch my webpage again...
Can anyone shed some light on this issue? Or is there a
better way to
display my results so that what i get back with my query will
always
display....
here is my stored procedure that im calling
SET NOCOUNT ON;
SELECT
c.cfname,c.clname,c.cid,h.termcode,h.hiredate,h.lastdate,h.cdateh,
h.cdatet,h.startdate,h.managername,h.termby,
availsun1,availsun2,availmon1,availmon2,availtue1,availtue2,
availwed1,availwed2,availthur1,availthur2,availfri1,availfri2,
availsat1,availsat2,h.comby,ssn_dash = dbo.SSN_dash(cssn),
Home = dbo.PhoneNumber_complete_format(chphone),
Mobile = dbo.PhoneNumber_complete_format(cmphone),
Other = dbo.PhoneNumber_complete_format(cophone),
Jobtitle =
case
when c.st = '90' then
(select top 1 j.jobtitle from has.dbo.JobCodes j where j.hjob
= h.jobid and
j.hlocation = 'DC')
else
(select top 1 j.jobtitle from has.dbo.JobCodes j where j.hjob
= h.jobid and
j.hlocation <> 'DC')
end,
(Select T.term_reason
From has.dbo.termcodes T, has_arc.dbo.EmpTermHistory H
where T.term_val = H.termcode and h.cid = @cid) as
TermReason,
Days = @day,
Months = @month,
Years = @year
FROM has_arc.dbo.EmpCandidate C, has_arc.dbo.EmpTermHistory H
WHERE C.cid = @cid AND C.cid = H.cid
END
ASP, SQL2005, DW8 VBScript

And when it says read the columns left to right... i would
imagine that
means my select statement should select the columns in the
order of which
they are in the tables?
so in my case.. if HomePhone is last column in my table it
should be the
last in the select statement?
