Unable to develop universe on top of my BW query

Dear all expert,
I have the following situation. i have a BW query, i have check the "allow external access". but when i want to develop the universe on top of it, it show me empty field. then i try to develop a crystal report on top of it, but when i search the query, i did not see anything.
How could this happened? the previous query that i had develop and check the " allow external access" option, i can develop universe or CR with it.
Thank You.

Hi,
is the user allowed to see the BEx query ?
can the user see the query in transaction RSRT ? in transaction MDXTEST ?
did you check the authorizations ?

Best practices to create Universe on top of SAP BW

Hi Experts,
I would like to know the Best Practices for Creating Universe on top of SAP BW.
1. is it advisable to create Universe on top of SAP BW CUBE directly. in my case , we are starting a fresh BW implementation for one application on SAP BI.7 ; and BOE 3.1
2. if we create a universe on top of BEX Query, what need to be done if want to upgrade to Business Objects 4.0 version.
3. if we create a universe on BEX Query, will SAP is going to support universe on BEX for future releases.
4. what is the support period for BEX and its integration with Business objects.
Thanks
Bhnau.

Hi,
1. is it advisable to create Universe on top of SAP BW CUBE directly. in my case , we are starting a fresh BW implementation for one application on SAP BI.7 ; and BOE 3.1
First go through by below link.This guide describe how you can create universe based on Cube and Query and what features are available via Cube and Query.
http://help.sap.com/businessobject/product_guides/boexir3/en/xi3_sap_olap_universes_en.pdf
You can check on the Page 12 in the PDF what supported by Cube and BW Query while designing of a universe.
Best practices says to design universe on top of one generic query for one Cube because CFK,RFK can not generate in the universe on top of BW Cube.
2. if we create a universe on top of BEX Query, what need to be done if want to upgrade to Business Objects 4.0 version.
check below links.

Create a Universe in top of a Webservice

Hi , is it possible to create a Webintelligence universe in top of a webservice ??
Harald

Hi,
The answer to your question is, no.
To report from SAP BI, you would need to have the integration between BI and BO set up, a bex query and then create the universe on top op the bex query to get the data out and use it in Webi.
Hope this helps.

Unable to use SSO with universe connection on top of SAP BW query

Hi,
We're creating a universe on top of a SAP BW query by using universe designer.
We logon to universe designer by using SAP credential.
When creating the connection, we set the option "Use Single Sign On when refreshing reports at view time" in order to logon to BW server. But when clicking next, an error arises:
"DBD: Unable to connect to SAP BW server Incomplete logon data"
The strange thing on this is that there is one laptop which is able to set up this kind of connection, while all other workstations are not able to set it because they recieve that error (we all work against the same BO server). So this looks like an installation issue.
We reinstalled SAP Integration Solutions on those workstations, but problem is still the same.
I found thread: Universe Connection Authentication on SAP BW which talks about the same issue, but solution involves uninstalling Xcelsius. But we do need Xcelsius!
Any suggestions?
Thanks,
David.

Unable to collect universe information

We have installed Information Steward 14.2.1.220
I have created a Integrator to collect information on BI4.1 environment, when the integrator is scheduled, run is successful and universe information is not loaded to database tables.
Following distinct warnings/Errors are raised.
1. [W] 2014-05-22 08:41:00.018 Unable to collect universes.java.net.SocketException: Connection reset (CMM-10273)
2. [E] 2014-05-22 08:41:22.341 Universe [/Universes/eFashion]. Failedto collect metadata for Universe Unknown Error : eFashion (CMM-10117)

Note:
1. No extra content is developed in this environment only default
universes and reports along with installation are present in system.
2. Administrator user is used to configure Integrator.
3. Also tired to add some universes and reports and same errors/warnings while running the integrator.
Environment Information:
Business Objects:
SAP BusinessObjects BI Platform 4.1 Support Pack 2 Patch 3
Version: 14.1.2.1216
Information Steward:
SAP Information Steward Version: 14.2.1.220
Can someone help me in fixing these issues.
Thanks,
Suresh.

Hi Suresh,
As per the log you attached, the following i understood,
1. Unable to collect Universes - Due to Connection Reset
2. Failed to collect metadata of Universe eFashion
3. Webi Document - Unable to define relationships with Universe - Due to Class is not exists in Universe
And you clearly mentioned that, nothing new developments are there in BI system and you used Administrator account to extract the metadata.
Suresh, you please do the following tests, which will help you to fix the issue:
Log in to IS Server, where you installed the Metadata Integrators,
1. Try to access the Universe eFashion from IDT / UDT tool
2. Perform Integrity Check on Universe (especially check the Connection Test is passed or not)
3. Check the Business Layer of eFashion Universe, whether all the classes are exists or not
4. Open the eFashion related WebI document in Rich Client and run the report to check whether the report is running or throwing an error.
These test will help you to find the root cause for the above issue.
Thanks,
Ramakrishna Kamurthy

Are there any (dis)advantages in building a universe on fully normalized tables instead of building dimensional model/tables and then universe on top of them?

Hello,
I’m hoping someone can help me with understanding advantages and disadvantages if we want to build a universe on top of a fully normalized tables, compared to using a dimensional model with star schemas.
I’ve read some discussions here that say that it is possible to create a universe on top of normalized tables. Then, can we avoid building of dimensional tables (a data mart), and just use normalized tables? I would say that it is easier to use star schema dimensions and facts tables to build a universe, but our end users might ask “why do we have to go through building a dimensional data mart, if we can have same reports with hierarchies and drill-down functionality based on a universe built on top of our already existing normalized tables?”
Can you point me to some established best practices regarding using normalized tables to build a universe? Any documents with some examples for this?
Any expected difficulties during design/development phase of our universe, related to using normalized tables?
Any expected performance degradation if we use normalized tables compared to using dimensional tables?
Can I build universe more easily if I transform (modify) our normalized model (by using alias tables and views) to look like snowflake model?
I’m using BOE XI 3.1, tables are in Oracle 11.2.
Thank you

Few Disadvantages that I usually face when building universe on Normalized tables,
1. Performance - Read operations have to suffer because indexing strategies do not go well with table joins
2. Derived Tables - Due to complex Queries/ Logic, most of the time, end-up creating derived tables, which doesn't use back-end table indexes and slows down the report runtime.
3. Normalized table/ Transaction tables may not always have proper cardinality and often results in Cartesian products
4. Normalized tables may not have tight referential integrity and may have to join more than one column and join on varchar, etc whereas, good Dimensional model datawarehouse will have proper keys/ integer joins and not always necessary to join on multiple fields
5. Often deal with Fan and Chasm Traps
6. Dealing with Database fields with nulls, blanks, date in numeric format, etc.,
7. No Facts, Dimensions separated and most of the time they are in same table
and More...
If performance is not a matter and building Datawarehouse is a big deal, then I will start building Universe on normalized tables by having the database diagram as reference for Joins, contexts, etc
Note: After dealing with universes based on normalized tables for few years (by creating views, complex sql queries data loading to tables and unv on these tables, derived tables), I ended up creating star-schema dimensional model (couple of months extra ETL work), users/ developers felt lot better when they have to create standard/ ad-hoc reports and they are super fast compared to previous universes.

Hierarchies on Universe on top of MSAS cube

All,
I have created an Universe on top of a MSAS 2005 cube. I am using BOXI3.1 base version.
1. I noticed that none of the already predefined hierarchies in the cube get automatically set as custom hierarchies in the BO Universe.
I would need to manually set the hierarchies again on the Universe. Is this working as designed or am i missing something here?

Thanks Didier.
However if i activate the drill-down in a webi report based on cube universe , i am unable to perform any slice/dice or drilling based on these default hierarchies.
Just to rephrase the question: the MSAS cube has these custom hierarchies which you can use through proclarity or excel..however when universe is created on top the cube..those custom hierarchies are not flowing in as a part of the creation.
Let me know if this is function as designed.

Custom Filter in Universe on top of BEX Query is not working in BO Explorer?

Hi,
I have created Condition(Filter) for an Dimension Object "Submitted by Group Hierarchy" in Universe designer tool on top of SAP BEx Query and then exported the universe to Repository.
<FILTER KEY="@Select(Submitted By Group Hierarchy\L01 Submitted By Group Hierarchy).[TECH_NAME]"><CONDITION OPERATORCONDITION="InList"><CONSTANT CAPTION="@Prompt('Submitted By Group ','A',' Submitted By Group Hierarchy\L01 Submitted By Group Hierarchy',multi,primary_key,,{‘Direct Sales’)"/></CONDITION></FILTER>
To test my custom filter , I have created WEBI report and its allowing input entry in my custom filter and output is also coming .
where as in Explorer, i am not able to enter input values for my custom filter as below.
Can anyone suggest me how to create custom filter in universe and use it in explorer.
Thanks in advance.

Ramana.

Hi Ramana,
Please try using 'mono' in place of multi in @prompt syntax and then test.

Universe on top of SAP BW

Hi Experts,
I need help in creating a universe on top of BPC Cubes.
While creating Universe connection, I have followed the steps below:
1. Connection type:
SAP BusinessObjects > Business Planning and Consolidation > OLE DB for OLAP Providers
2. Username: DOMAIN\USERNAME
3. Server: BPC Server IP Address (tried with port as well)
Then I am getting the following error:
DBD: An error has occurred while attempting to connect to the OLAP server. Failed to initialize (returned server error (Returned DB_SEC_E_AUTH_FAILED (0x80040e4d)))
Any Idea where I am going wrong ?
Product Versions:
SAP BPC 7.5 SP 07
BO XI 3.1 SP2 FP 2.9
Thanks and Regards,

Hi,
Could you give more details around what host file you are refering to? As I have the same error message.
Thanks

Strange issues in WebI report on standard Universe on top of BW Query

Hello,
We have a BW query with a standard Universe on top of it (generated automatically via the connection in universe designer).
However, very strange things happen when playing with the data in WebI.
There are some characteristics and just one key figure (which is just 'number of records').
- key figures just disappear when adding characteristics
- the wrong assignment is made from the infoobject to a dimension in webi when combining several characteristics in the WebI report (for example the 'customer' field holds the 'date' and the 'date' field is empty.
I think it has something to do with BO that starts from the text of an infoobject instead of from the key.
Also I constantly have to refresh the data when adding fields to the report.
Did anybody have similar issues? How did you solve them?
I also tried 'restructuring' the universe by deleting everything that's less relevant for the report, and taking the longest available text as dimension with key of the info object as detail and this seemed to work a lot better. However we shouldn't have to restructure a universe that's generated from a query?
Thanks,
Tom

We had a the same thing. Assuming it is the same cause, it is a known issue. SAP had us install two Notes on BW and the problem disappeared.. Evidently it has to do with an MDX generation problem. See response below and do some investigation.
This is a known issue.
Here are the notes that fix this issue. The second note has two composite notes in it that will need to be applied as well if they still have problems after they install the first two.
There are some items that are broken in SP6. You'll notice that SAP note 1404328 is already in SP6. You'll still need to install it again along with the second SAP note 1420169
Please install both of these and try your work flow again. If it's still not working, then you'll need to go through the composite notes in the second SAP note 1420169.

Problem with automatic creation of Universes on top of SAP BW - RKF

Hello
When I create Universes on top of SAP BW Querys everythings works fine, except for the Restricted Key Figures. The RKFs are created with the GUID code and not with the Description configured in the Query. I tried making the Key Figure Local and Global in the query without success. Does anyone know what's happening?
I'm using BO XI 3.1 SP2 with SAP BW 7.0.
André

I created universes based on a BW Query in the following situations:
    User specified username and password:   language = PT - Dimension's name OK, RKF are GUID
    User specified username and password:   language = EN - Dimension's name OK, RFK are GUID
    SSO: langue = PT or EN - Dimensions name are Ok and in English - RFK are GUID
I edited prefences of CMC to Portuguese. The same results.
The problem with the RKF still exists.
Is there some way resolve this problem?

Dispaly attribute not available in universe on top of BPC cube

Hi,
I have created a universe on top of a BPC cube.
The cube has a dimension object which has display attributes associated with it.
In the universe, dimension objects are automatically created for the dimensions. But no detail object has been created for the display attributes.
Is there any way to make the display attributes available for reporting ?
Thanks and Regards,
PASG

By having BEx queries on BPC cubes, I thought the revenue will be negative for example and balance sheet items will be double counted over time. I am not sure if SAP is officially supporting this BEx on BPC cubes ?
When I get data from Legacy systems into BW cubes, I would like to validate( and raise exceptions if required) the imported transactional data. Any other way to accomplish these with BEx queries on BPC cubes ?
