Bad performance of Java Web Report in BI 7

We are experiencing poor performance with Java web application(EP)
comparing to that with ABAP web.
We migrated our BI reports from the ABAP web interface to the Java web
interface due to our upgrade to Netweaver2004 environment.
The problem is that it takes much longer time to load the BI reports in
Java web than in ABAP web.
It is the same situation in RSRT. Java web needs more time to execute
the same query.
there is no EP logon performance delay, so I think the EP is configured good.
But the response time of BI Java Web Report is delayed average of 4~5
seconds in every Query compared in that of ABAP Web report.
Anyone experience this situation?

Hi,
I am facing similar problem. How did you solve it?

The action cannot be performed error for Webi Report

HI,
I am getting the error The action cannot be performed error for Webi Report. I am getting this error after i save the report and open it again.

This is happening for only 1 particular report. In the end i removed some of the objects from the query and added some new ones.
Strangely it worked!

Performance Issue with Webi report uses SAP BI Query as the data source

Hello.
I have created a Webi ad-hoc report which connects to a SAP BI query through BO OLAP universe.
The layout of Webi is the exactly the same as the BI query. There are filters in the Webi to restrict the number of data extraction, but even with data result of 5000 rows, it took about 30 seconds.
If I execute the BI query with the same filter restriction, it tooks less than 10 seconds.
It seems that large percentage of time is consumed at the MDX part.
Is there any tuning method that could speed up the process time of MDX?
Thank you.

Hi,
please take a look here:
[https://service.sap.com/sap/support/notes/1142664] (Look under related notes)
It includes references to various performance improvements of the MDX interface. From what I saw there it is advisable to upgrade your SAP BI (7.0) up to at least Support Package 21 (you are currently on SP 15).
This may also be interesting for you: There is a new Fix Pack 1.4 coming out for BOBJ XI 3.1. Combined with the related SAP Enh.Pack (not sure about the version of this one) should also improve WebI performance. This fix pack is not yet officially released though but it should not take look.
I recommend that you try the upgrade to Support Package 21 first.
BTW it is also advisable to take a look in the results of your MDX query (e.g using the MDXTEST transaction). You should make sure that your query is indeed restricted as expected. Sometimes the results you see in SAP native reporting tools (e.g. BEx Analyzer) differ from those returned from the MDX component, depending on the way variables/restrictions where defined in the query designer. It is all about making sure that there is no apples/oranges comparison here.

Performance Tuning of webi report BO4.0

Hi ,
I have report which has two data providers in 1st Data Provider i have 10 objects and in 2nd Data provider i have 3 objects the issue is performance report is taking 6 minutes to run.
Please help me out how we can increase the performance at Query Level.
Thanks
Siva

Hi
There are various levels to which you have to check to improve the performance of reports could be at connection levels, query, database etc.
some of them you can try
1. check array fetch size in relational connection parameters, deactivating array fetch size can increase the efficiency of retrieving your data, but slows server performance.
2. Setting options for the default list of values in business layer and data foundation layer
Automatic refresh - If this is selected, the list of values is automatically refreshed each time the
list is called. This can have an effect on performance each time the list of values is refreshed. You should disable this option if the list of values returns a large number of values.
3. set query stripping (Optimize query with Query Stripping in Web Intelligence - Business Intelligence (BusinessObjects) - SCN Wiki)
4. also check Performance Tuning Methods in BO

Bad performance in web intelligence reports

Hi,
We use Business Objects with Web Intelligence documents and Crystal Reports.
We are supporting bad performance when we use the reports specilly when we need to change the drill options
Can someone telling me if exists some best practices to improve performance? What features should i look to?
                  Best Regards
                        João Fernandes

Hi,
Thank you for your interest. I know that this a issue with many variables because that i need information about anything that could cause bad performance.
For bad performance i mean the time that we take running and refreshing reports data.
We have reports with many lines but the performance is bad even when a few users are in the system
                             Best Regards
                                     João Fernandes

Bad performance when deleting report column in webi(with "Design – Structure only")

Hi all,
One of our customer has recently upgraded from BO XI to BO4.1. In the new BO 4.1, they encountered a bad performance issue when they were deleting a column in Webi(using "Design – Structure only" mode).
With “Design – Structure only" mode, it took webi about 10 seconds to complete after the customer right-clicked a report column and clicked the "delete". The customer said that they only need to wait for less than 1 second when they did the same in BO XI old version.
The new BO version used is 4.1SP02, installed in Windows Server 2008 R2. (Server with 32 core CPU, 32G memory)
This bad performance happened in both Webi web and Rich Client. (in Webi Rich Client, the performance is a little bit better. The 'delete column' action takes about 8 seconds to complete).
Do anyone know how to tune this performance in webi? Thank you.
Besides, it seems that each time we are making change in the webi report structure in IE or Rich Client, webi need to interact with Server site to upload the changes. Is there any option to change this behavior? Say, do not upload change to Server for when 'deleting report column', only trigger the upload after a set of actions(e.g. trigger when click the "Save" button).
Thank you.
Regards,
Eton.

Hi all,
Could anyone help me on this? Thanks!
What customer concerns now is that when they did the same 'column editing' action in BO XI R2 for the same report, they did not need to wait. And they need to wait for at least 7-8 second in the BO 4.1SP02 environment for this action to complete.(data already purged, in structure-only mode)
One more information about the webi report being editing is: there are many sheets in the report(about 6~10 sheets in one report). Customer don't want to separate these sheet into different reports as it will increase the effort of their end users to locate similar report sheets.

Eton.

2004s Web report performance is not good ,though that of 3x web is OK.

Hi,
I feel 2004s Web report performance is bad, though that of 3x web is no problem (the same query is used.) it is worse than BEx analyzer.
This query has more than 1,000 records and those queries that have many records result in the same bad performance.
Of course there are many reason for this bad performance, please tell me your solution by which you solve the same problem like this.
the SIDs of EP and BI is difference here.
CPU is not consumed when 2004s web report is executed.
And I have cancelled virus scan to this web report...
Kind regards,
Masaaki

It is bad, am sure it's down to the new .net and java based technology. Aggregates are a way forwards though from what i've heard of the BI Accelerator this is the real way forwards.

Report Result differs between Java Web and ABAP Web

Hi Experts,
We have a BW Report in BI NW 7.0. When we run the report in Bex (ABAP Stack) or ABAP Web the default results are different from the Java Web Results. There are no selection differences.
Please help me if I miss any settings or any corrections required.
Thanks in advance.
Deepthi.

Hi,
The function Calculate Results as ... could not be applied everywhere.
Recalculation of a resutls row is always based on the amount of detail cells subordinate to this cell, which is the finest details of a drilldown. It is not possible to recalculate resutls in hierarchical lists. This means that calculation of a results cell is not performed if a row or column with an expand symbol is subordinate to it. With recalculation, the newly calculated result has to change with each expansion of a node subordinate to it. This is not supported for technical reasons and would only confuse the user.
Note, however, that Calculate Results as -> Suppress Results is always executed, because the problem above does not apply in that case.
Notification Number BRAIN 141
Please refer the notes
Note 1071067 - "Calculate Singlve Value as" in list without drilldown
Note 997421 - Calculate as 'Supress Result' on hierarchy nodes
Note 857895 - 'Suppress results' for the display hierarchy
Note 853058 - Calculate Results/Single Values as ... priority rules
Hope this helps.

Webi Report Performance issue as compared with backaend SAP BW as

Hi
We are having Backend as SAP BW.
Dashboard and Webi reports are created with Backend SAP BW.
i.e thru Universe on top of Bex query and then webi report and then dashboard thru live office.
My point is that when we have created webi reprts with date range as parameter(sometimes as mandatory variable which comes as prompt in webi) or sometimes taking L 01 Calender date from Bex and creating a prompt in webi, we are facing that reports are taking lot of time to open. 5 minutes 10 minutes and sometimes 22 minutes to open.
This type of problem never ocurred when Backened was Oracle.
Also when drilling in webi report,it takes lot of time .
So can you suggest any solution?

Hi Gaurav,
We logged this issue with support already, it is acknowledged.
What happens is that whenever you use an infoobject in the condition
(so pull in the object into condition and build a condition there,
or use that object in a filter object in the universe and then use the filter)
this will result in that object being added to the result set.
Since the query will retrieve a lot of different calendar days for the period you selected,
the resultset will be VERY big and performance virtually non-existent.
The workaround we used is to use a BEX variable for all date based selections.
One optional range variable makes it possible to build various types of selections
(less (with a very early startdate), greater (with a very far in the future enddate) and between).
Because the range selection is now handled by BEX, the calendar day will not be part of the selection...
Good luck!
Marianne

Performance issue and data getting interchanged in BO Webi report + SAP BW

Hi,
We are using SAP BW queries as the source for creating some BO reports.
Environments :
SAP - SAP BI 7.1
BO - BO XI 3.1
Issues :
The reports were working fine in Dev and Q with less data. But when we point the universes to BW prod ( where we have much data), the reports are taking quite a long time to refresh and getting timed out. This query has some key figures which are having customer exits defined to show only one month data. And also BW accelerators are updated for the infocubes pertaining to this query. The BO report is giving data if we apply a filter in 'Query Panel' of Webi to show only current month dates. But then the issue is the values are getting interchanged for many objects. For ex: there are 2 objects- ABS version and Market region. The values are getting interchanged in the BO level.
Please let us know if anything needs to be done in BO or BW to fix this issue if anyone has faced the same
Also Please let us know if customer exits and accelerators works fine with BO
Thanks
Sivakami

Hi,
Thanks Roberto. We'll check the notes
@Ingo,
We are able to solve the performance issue by removing unused Key figures and dimensions from the query, but the column value interchange issue still persisits
The build version is - 12.3.0
Query Stripping
Where should we enable query stripping? When i went through some documentation it was written that it'll be enabled automatically from XI 3.1 Sp3. Can you please let us know if its so and what we need to do to enable it.
The coulmn interchange is happening when we use dimensions in a certain order. When product type is used along with Market region. Market region shows values of Product type also in Webi report.
Thanks & Regards,
Sivakami

Bad performance when open a bi publisher report in excel

We use bi publisher(xml publisher) to create a customized report. For a small report, user like it very much. But for a bigger report, users complain about the performance when they open the file.
I know it is not a native excel file, that may cause the bad performance. So I ask my user to save it to a new file as a native excel format. The new file still worse than a normal excel file when we open it.
I did a test. We try to save a bi publish report to excel format, the size shrink to 4Mb. But if we "copy all" and "Paste Special" value only to a new excel file, the size is only 1Mb.
Do I have any way to improve that, users are complaining everyday. Thanks!
I did a test today.
I create a test report
Test 1: Original file from BIP in EBS is 10Mb. We save it in my local disk, when we open the file, it takes 43 sec.
Test 2: We save the file in native excel format, the file size is 2.28Mb, it takes 7 sec. to open.
Test 3: We copy all cell and "PasteSpecial" to a new excel file with value only. The file size is 1.66Mb, it takes only 1 sec to open.

EBS or Standalone BIP?
If EBS see this thread for suggestions on performance tuning and hints and tips:
EBS BIP Performance Tuning - Definitive Guide?
Note also that I did end up rewriting my report as PL/SQL producing a csv file and have done with several large reports in BIP on EBS.

Scheduling webi reports via Java SDK in BI 4.1

Hi,
Has anyone been able to schedule a Webi report containing date prompts via Java SDK in BI 4.1? I have tried doing so but it doesn't work when date prompts are involved, I get the exception raised: java.lang.NullPointerException error. Though the scheduled instance is created and the date prompt appears to be correctly populated the report fails with the above mentioned error message. The code is working for other text prompts but fails when I have a date prompt in the report. I am using the populateWebiPrompts() method to populate the prompts.
CF

Hi Christopher,
Try adding the following line in your code before scheduling:
iWebi.setUserInputLocaleName(documentInstance.getProperties().getProperty(PropertiesType.BASE_LOCALE));
Also as an FYI, please refer below details.
For scheduling webi reports with prompts, the only supported way is to use Restful webservices SDKs.
The feature of scheduling a webi report with prompts were deprected from release BI 4.x and introduced in the new restfull webservices. Restful is the future which SAP is focussing and would be great to have your application on supported terms with SAP.
You can get details about the restful webservices from the documents and blogs available at below forum
http://scn.sap.com/community/restful-sdk

Reporting on master data customer and bad performances : any workaround ?

Hello,
I've been asked to investiguate on bad performances encountered when performing reporting
on the specific master data zcustomer.
Basically this master data has a quite similar design that 0customer, there are 96000 entries in the master data table.
A simple query has been developed : the reporting is done on the master data zcustomer and its attributes : no key figure, no calculation, no restriction ...
Nevertheless, the query can not be executed .. the query runs around 10 minute in rsrt, then the private memory is exhausted and then a short dump is generated.
I tried to buid a very simple query on 0customer, this time, without the attributes ... and it took more than 30 sec before I get the results.
I checked the queries statistics :
3.x Analyzer Server 10 sec
OLAP: Read Texts : 20 sec
How is it that it is so long to performthe reporitng on those master data, while in the same time If i try to display the content in SAP by choosing "maintain master data", I have an immediate answer.
I there any workaround ?
Any help would be really appreciated.
thank you.
Raoul

Hi.
How much data have you got in the cube?
If you make no restrictions, you are asking the system to return data for all 96.000 customers. That is one thing that might take some time.
Also, using the attributes of this customer object, fx making selection or displaying several of them, means that the system has to run through the 96.000 records in masterdata to know what goes where in the report.
When you display the masterdata, you are by default displaying just the 250 or so first hits, and you are not joining against any cube or sorting the result set, so that is fast.
You should make some kind of restriction on other things than zcustomer (time, org.unit, version, etc, to limit the dataset from the cube, but also a restriction on one of the zcustomer attribs, with an index for that maybe, and performance should improve.
