Performance - Crystal on top of BEx against Cube - Universe - WebI

Hello All,
We are using Crystal Reports built on top of BEx queries. The BEx queries use aggregates and we have a good performance. My question is
Can we create an Universe on top of Info Cube and build WebI and expect the same performance as we get now? I have not seen any documentation about the BIA or Aggregates are being used by Buiness Objects yet. Could anyone throw some light at this?
Thanks,
Arthur.

Hi,
you would build a Universe on top of the BW query and the query would still use the aggregates from your BW system like it was doing that before.
aggregates and the usage of BIA are transparent to the BusinessObjects tools.

WebI performance - Universe built on BEx against an Info Cube.....

Hi,
I am using SAP BI for some time now. I know after the introduction of BIA (BI Accelerator) the performance of any query has increased atleast 90% from what it used to be. The OLAP performance does not change, but the data retrival (DB Read) has almost negligible.
My question is for some one who is using WebI on top of an Info Cube and on top of a BEx Query.
The performance will be almost comparable of a Web I created on top of a BEx query, because it will still use BIA.
The performance of a Web I document will not be anywhere close to the above when the universe is created on top of an Info Cube, because it cannot use BIA.
Can anyone validate the statement?
Thanks,
Alex.

Ingo,
As mentioned earlier, I too am grateful for your willingness to share your knowledge and insight on the SAP BusinessObjects product.
As a point of order, I was wondering if I could stick my neck out a moment. I notice that your username is marked as a mentor and SAP Employee, so perhaps you can lend a hand here. It seems that "Alex Arthur Sam", in another posting asked a question, then stated he had "found answer.", and after several postings going back to over a year ago, he has not responded. Is there some type of sanction we, as participants, can appeal to so that they can either gently ask Sam to respond or limit his access to the forum as a participant for a period? I know I don't have a dog in this fight, but some day in the future I may be facing a similar situation and am wondering what the SAP Community Network moderator's stance is. Believe it or not, I have worked with clients who, though don't question my abilities, perform their own research on forums such as this to verify when I say such-and-such cannot be done. When they see that others have "achieved the impossible" they expect me to "get to it likewise". Forums seems to be either a boon or rue, but with a moderator's help from time to time the forum can be more bearable otherwise.
Thanks for giving a listen and I (and I'm sure others) await your response.

P.S. The note in question is: [Instead of 0FI_GL_14;

Crystal report showing Incorrect data against Bex Query

I have created Crystal report on top of Bex Query, I have not done any calculations in the report, just dragging structure and key figure in the report, ran for one month, when I compare with Bex Query with same period, it is showing incorrect data.
I don't know what can be wrong here?
We are Business Objects 3.1 SP3.
Thanks,

Query performance for WEBI on top of BEx

Hello Everyone,
Is there a way to get the time taken by a webi query execution on the BO side and in the BW side? Is this stat stored some where?
Also, what is the best approach to take for comparing performance between the original bex query and the WEBI on top of the Bex?
Thanks for your help.

Hi,
i posted some links for the same Question here:

Report performance while creating report on BEx

All all!
I am creating a report on BOE 4.0 on top of BEx connection as a source. I have developed reports on top of universe in the past and i know that if we keep calculations on reporting end it hampers the report performance. Is this the same case with BEx? if we are following the best practices is it ok to say that we should keep all heavy calculations/ aggregation on BEx or backend for better report performance.
Can you guys please provide your opinion based on your experiance and knowledge. Any feedbacks will help! Thanks.

Hi,
Definitely best-practice to delegate a maximum of CKF to the Cube where possilble, put RKF in the BEx query, and Filters too.
also, add Default Values to your Variables (this will speed up generation of the bics transient universe)
also, since Patch2.10, we are seeing some significant performance improvements reducing 'document initialization' and 'time to prompts' by up to 50% (step such as these often took 1.5 minutes, even on sized systems)
Also, make sure you have BW corrections like this implemented: 1593802 Performance optimization when loading query views
In the BusinessObjects landscape - especially with BI 4.0 - it's all about Sizing and Tuning . Here is your bible the 'sizing companion' guide : http://service.sap.com/~form/sapnet?_SHORTKEY=01100035870000738725&_OBJECT=011000358700000307202011E
Pay particular attention to BICSChunkSize registry settings
Also, the -Xmx JVM Heap Size for the Adaptive Processing Server that is running the DSL_Bridge service.

Will it make any sense to create materialized view on top of a MOLAP cube?

Hi,
We have developed few MOLAP cubes for our reporting environment.
Now we are planning to create materialized with query rewrite enabled for faster performance?
Is this a correct approach? Will it make any sense? I mean will i get any performance improvement if i create MV on top of a MOLAP cube?
Thanks and Regards,
Padmanabh

Adding a rewrite MV does not change the raw performance of a cube. The only reason to add one is if you want to write your SQL queries against the base relational tables and have the database rewrite your queries against the cube. If you are able to query the cube views directly, then there is no particular benefit to a rewrite MV.
Adding a refresh-only MV does have benefits even if your queries use the cube views. A refresh-only MV tracks the staleness of the cube and lets you run 'fast' refreshes, which can be useful if you are only modifiying a handful of rows in your fact table.

Can I create one single crystal report using 2 bex queries

HI all,
I have 2 bex queries and has to develope a single crystal report .Is it possible???? If so, than how to connect two bex queries and develope one single crystal report.Any other option is also fine. I mean ....no need to use crystal..( I can go for one single webi..).But need to know the approach ...
or else...can I create universe on 1 bex and other universe on other bex ..and go for one single webi report..
Only problem is client is particular about one single report(either crystal or webi)
if i go for webi ...I know we can use link universe option but I dont know whether it works fro OLAP environment.
Please let me know if I can link OLAp universes and go for 1 single webi report.
Any help is appreciated.
Thanks in advance,
Mahathi

You can use either CR or WebI.
In CR Designer create the report using the SAP toolbar (Create report from query) based on the 1st BEx query. Then use the Database expert (first entry in the Database menu) to add an additional connection to your 2nd BEx query (+Create new connection->SAP BW DX query). You can then join the results of the 2 different queries in the database expert also.. Please note that if you do NOT want to join the result sets, then it is more efficient to use subreports. Create two different CR reports, each based on one of the BEx queries and then use one of those as your main report and insert the other one into it as subreport. Once embedded you do not have to keep the separate .rpt file of your second report.
For Webi you must build 2 universes, each based on one of your BEx queries. In your report you can add multiple queries based on different universes. You can join the results sets here by using the Merge dimensions button in the report editor area.
Regards,
Stratos
PS; Keep in mind that joining a large number of rows at report level (either in CR or WebI) can cause performance problems. If this is your requirement, how many rows do you expect to get back from each individual query?

Webi on top of Bex query, maximum of fields 50 limit

Hi there,
I'm creating the Webi Report on top the Bex Query that has 50 characteristics in the row area and around 10 characteristics in Free Characteristics area. (Bex query can't have more than 50 in the Row Area)
When I create the WEbi report, it limits the output to the same 50 characteristics, it means that even though I have 10 more characteristics available from the Free Characteristics Area and I can't add them to the Webi Report.
I'm new to Webi and I didn't know about this limitation of number of fields can be added. Is there a workaround for this case?
Is 50 fields really a limit for Webi Report or am I doing something wrong here?
Thanks!

Hi,
Much like BEx, with WebI it is recommended to not have more than 50 dimensions selected into a single OLAP query, otherwise performance will degrade.
I have customer who try to put 80-200 objects into webi query panel and get angry when they can't...
However, this is a silly thing to do. For example, how many people can read tables with 80 columns?
It usually mean that the business requirements aren't being focused enough, and that reports are trying to answer too many flexible u2018ad hocu2019 purposes.
To conclude, it's an u201Cirrelevant testu201D because WebI isnu2019t a u2018data dumpu2019 tool. you should perhaps use a genuine ETL to extract records for hundreds of objects

HI,
in the universe you have a dimension objects (blue objects) showing the description and a detail objects (green objects) showing the key.

How to remove Decimals in Quantity Objects in SAP BO Explorer View created on top SAP Bex Query?

Hi,
I created SAP BO Explorer report on top of SAP BEx Query.
In SAP BEx Query, Decimals were hided but when i created OLAP Universe on top that SAP BEx Query and Created Index on top of Information Space in SAP BO Explorer and then created Exploration Views. But i'm getting Decimals in my Exploration Views where as SAP BEx Query in RSRT, no decimals were appearing.
Can anyone suggest me how to remove decimals in SAP BO Exploration Views.

Hi Ramana,
I am not use how you connect to SAP BEx query (Via universe or BWA or HANA)
What I could say is BWA and HANA, you cannot adjust this
For universe, you could try in universe layer, there is note about this
For BWA and HANA, this function might be enhanced but you 'd better raise OSS to SAP to check with them
Best regards

How to bulid a Crystal report based on Bex query as source

Hi,
I have requirment where the end user wants the query in Crystal.I built a Bex query in Bex query designer.I would like to know how to create crystal report based onthe Bex query.
Thanks,

Hi
The Crystal Reports are integrated with BW such that the query built in BW can be used to bulit Crystal Reports on them.
After launching the Crystal Reports, you will have and option : "Open reprt from BW" whcih will help you in opening the BW Queries and create Crystal Reports.
Also in the Menu there is an optin SAP-->Create New Report from a Query

WebIntelligence report on top of bex Query in BI4.0 (SP2)

Dear experts,
I'm working on webi report on top of bex Query in BI4.0 (SP2). I would like to know your opinions about some points I have noticed.
A - I need to drill throught a hierarchy which contains several millions of members.
Is there a possibility in my report drilling down to one member without selecting all members of the hierarchy in the query panel ?
B - I cannot put a dimension with hierarchy both in the result pane and in the filter pane, although it is possible for any other dimension without hierarchy.
Is there any special trick to achieve this or is a bug??
C - I cannot sort variables defined in my bex query, but they don't appear in the window to sort prompts.
Do you know how to solve this issue ?
D - I noticed all keys and description of dimensions appear with the same label "key" and "text". SO it is very confusing for the user to understand what key or text means (if a key if the customer key or the company code key).
Any idea to have a more explicit label for BW characteristics?
Regards.
CL.

Hi,
I do not have access to a BW system to test this, but i have something on three of your questions...
A) drilling without getting all the lower members. I would look to query drill, this means a drill action in the report will go to the database to fetch the level (and only for the selected member, a drill down).
The only thing I'm not sure about is if the BEx hierarchy is seen as drill hierarchy by that option too.
If you'd ask me it really should.
C) this is an old problem, but I know it is bugging more people, because the same is true for universe based prompts. They also cannot be 'arranged'. Since the Bex query is the 'universe', ordering that has been set in the 'universe' is the only chance you have.
Like with the universe you could use prefixes to separate them from the query defined prompts (based on an alphabetic sort of the prompt message). I'd say this is a good one for the idea place...
D) also an old (very old actually) problem. Some will want to keep the text short and simple. The prefixing will tell which key it is. Some will prefer unique names, so no prefix is needed. The same was true for universe designers. Now since there is no universe, if you do not agree with the 'designer' you're out of luck no way to change it.
Hope this helps,
Marianne

Trouble displaying Period Depreciation in query against cube 0FIAA_C02

Hello,
I'm quite familiar with writing queries, however and I'm having trouble displaying "Period Depreciation" in a query against cube 0FIAA_C02.
All charactertistics and most of the the key figure values appear with values displayed in the query....however any key figure that is to be related to "Period Depreciation" displays a zero.
Any thoughts on how I can display "Period Depreciation" from this cube?
Jim

Hi,
is the field "Period Depreciation" added to the cube or was it already in the business content ?
If it was added you can check if the value for "Period Depreciation" is correctly filled from within the update rule to the cube.
