Data Federator - BO Universe

Hi All,
Can anyone please explain me the benefit of using Data Federator as a connector between BO universe and BW system? Apart from getting the live data from the BW systems, does the Data Federator has any advantage?
Thanks in advance.

There is a discussion of this topic in the following SDN blog articles:
/people/thomas.zurek/blog/2009/03/06/better-performance-for-universe-based-access-to-bw

Data Federator data lineage and impact analysis

Hi,
I am looking for the use of data lineage and impact analysis feature in data federator at Universe level.
Can I know which objects are using which fields by uisng impact feature in the data federator.
Thanks in Advance.

I realize this answer is a cop out but I'll suggest it anyway. Upgrade.
I struggled with getting the lineage and impact analysis working in 10.1 and had to do quite a bit of trial and error in the Apache configuration files, DAD's ,etc. because the lineage reports were web based. I never got them working in Production due to other much more pressing implementation issues at the time and never went back to fix them.
In 10.2 and above the reports are much easier to get with no real configuration needed.
Anyway, back to your question, I would suggest going back through the 10.1 documentation on getting those to work and have someone a bit familiar with setting up Apache help you. I did get them working in our Test environment but its been so long I can't recall all the steps and tricks, sorry.

Data Federator connection from universe - commProtocol EBUS error

I am working with a prospect that is attempting to get a universe to communicate with DataFederator via JDBC. We modified the jdbc.sbo file and added the line
<Paramter Name="URL format">jdbc:datafederator://$DATASOURCE$;catalog'&quot';$DATABASE$'&quot';;commProtocol=EBUS</Parameter>
(single quotes were added above to preserver contents in quote marks, they are not really in the file)
along with the appropriate classpaths, per the XI3 datafederator release notes. However when the customer tries to connect via the connection manager in the universe the following error is thrown:
[Data Federator Driver] Invalid identifier for site wrapper in parameter 'commProtocol'. Reason: EBUS
Has anybody seen an error like this, and have any suggestion on how to correct it?
Thank you.

Hi Eric,
Can you tell me which version of Data Federator and BOE you are using?
It looks like you tried to configure Data Federator JDBC driver with a commProtocol that is not supported by this version of DF.
Are you using Data Federator XI 3.0 SP1 (12.1.0.0) or later version?
You can check the version of the Data Federator JDBC driver you are using by clicking "Test Connection" in Universe Designer. You will see the driver and database (DF) versions.
Make sure you are using the 12.1.0.0 version or later for both driver and server.

Data Federator Universe Date Functions

Hi,
I created a Data Federator Universe from target tables (Source Tables from: Sql Server 2005 and Oracle 10g). Now, I want to create a object in the universe: "Days between 2 dates"(coming from 2 different target tables). I don't see any other date functions other than CURDATE(). How to create my object?
Alternatively, Can I create a caliculated column in the existing target table? For Example, I want to create a new column "Days between 2 Dates" from 2 different tables by using a formula in Default mapping of the target table.
Thanks & Regards,
Peter

Hi Amit,
Thanks for your reply.
Ok. So, Universe on top of Data Federator has limited functionality.
And, other option you mentioned is on report level. I am creating an adhoc universe and I have few objects which will calculate days between 2 dates coming from 2 different tables.
But, how can I achieve this on Data Federator level. I have no function there to find Days Between 2 dates. I see lot of time and date functions but not the one I required. Also, I added a column in the target table and tried to apply the formula there in the default mapping area. But, I see only the selected target table. I need another date column from another table, which is not displayed in the default mapping area.
How can I achieve this?

Data Federator data source not available causes Universe Connection error

I created a Data Federator project that connects to 20 servers across US and Canada. All data sources are SQL Server 2005. The DF project maps 40 source objects into 4 target objects. I created a universe based on the DF project and we have been quite pleased with Webi query response. Today one of the source servers was taken off line and this generated a connection error when trying to access the universe (not trying to access the data source that failed). We do not want the universe connection to error when one source server is not available u2013 is that possible?
If the answer is no then I see us abandoning what appears to be a great solution for real time distributed reporting and resorting to ETL and moving data.

Hi Chapman,
Can you be little elobrate on what you have done to solve the issue.

Data federator Universe refresh issue

Hi all,
we are facing the issue refreshing the Universe which is based on Data Federator.
whenver the changes are done in BW Cube i.e adding the dimension or the keyfigure. the dimensionobject is not appearing in the Universe.even we delete the dimension or a key figure from BW and then refresh the dependent tables in DF . Deploy again the project,it is updating the catalog but when we refresh the Universe it is not refreshing properly
SO data federator and BW are in Sync but when we refresh the Universe it is not in sync
we are using BO XI SP3 and BW 7.01 SP7
I would really appreciate your valuable inputs regarding this issue

Data federator

Hello Experts,
I am just wondering how is Data federator to create Web Intelligence reports on top of SAP BW Infoproviders using Relational universe instead of OLAP universe.
My requirement is that we want to create universes with all the custom objects for calculations in it instead of creating them in bex query or in some in reporting level.
Please advise and also I would appreciate if some can please provide me some links on Data federator.
Thanks.
Rag

Data Federator uses the Data Federator facade to query the BW analytic engine, bypassing the OLAP MDX engine. It transforms the data into relational structures. You can then query these relational tables using a universe and webi.

Data Federator connecting to BW 3.5

I would like to use the Data Federator against a BW 3.5 system - is it possible to connect the DF to BW? Can someone help me with either documentation or how to do that. I'm currently using a OLAP universe and the performance is not very good
Thanks for the Help

Did you find a solution to this ?
there is a SAP to Data federator guide available did you try this ?

Data Federator 3.1

I could not locate Data Federator 3.1 on SAP SMP, only XI 3.0 and XI R2 are available for download.
Anyone has a link for DF 3.1 download?

Hi Gowtha,
an example of a DF setup looks like this
(ODBC 1, ODBC 2, ODBC 3) -> DF -> ODBC (OpenAccess Bridge) -> Universe
Once you install the DataFederator Drivers (Look for the subfolder in the folder you extracted the contents of the DF package) you will be able to setup an ODBC connection which allows you to access data within a DF project (you should be able to access all virtual tables and target tables defined there) from your universe.
Please check the DF user guide for more infos on this.

Data Federator and Information Design tool

Hi,
First, Can Data Federator be a single data source for Information Design Tool?
Second, from performance point of view, using Information Design tool to build multi-sources Universe or building Universe on Data Federator, which way is better?
Thanks

Hi,
let me explain :
in BI 4.0, the Data Federator Query Server engine is now part of the server-side Adaptive Processing Server .
You only invoke this architecture when you select "Multi Source Enabled" - any other entry point is NOT using the Data Federation Service.
So - if you select SingleSource - that's not using DF.
However, it is entirely possible to select "Multi Source Enabled" then only use 1 connection in the MSU !!
Having said the above, Your second question doesn't make sense.
Unless you mean, using the Data Federator middleware driver in BI 4.0 IDT, to connect to an XI 3.1 Data Federator Query Server? (i.e. consuming the 'old source' in the new enviornment)
This backwards compatibility was delivered to facilitate transition of DF customers, especially since there is no standalone DF product in BI 4.0 (yet)
I trust this is of use to you.

H

Data Federator question.

Can anyone explain the concept of using Data Federator. Does DF store data? Does DF harmonize master data at all?
Or is DF intended to just merge SAP BW transactional data with transactional data from other source systems?
We have SAP BW system and some other source systems to report from. We are being advised to use DF and develop relational universe over it.

Hi puneet,
DF does not store any data. As you mentioned in ur post, DF intended to just merge SAP BW transactional data with transactional data from other source systems.

Data Federator - Hierarchies and Text Descriptions

Hi,
I am trying to create WEBI reports on the top of SAP BW. The universe is connecting to SAP BW via Data Federator. I am facing issues with the hierarchy creation. The hierarchies created in the InfoProvider (Multicube - from CRM data source) are not available in the Universe. I can't create the hierarchies in the universe as all the levels of the hierarchy are not available in the multicube. I need to get the hierarchy data from the CRM data source directly. But the valid sources for DF with respect to SAP BW are just cubes. Kindly let me know if there are any workarounds. Please let me know if more details are needed.
Thanks in advance.
Regards.

Hi
Officially SAP BW hierarchies are not suppoerted for the Data Federator (http://wiki.sdn.sap.com/wiki/display/BOBJ/LeveragingDataFederatorinSAP+integrations). What you can do is to use also the SAP R/3 connector (SAP BusinessObjects Web Intelligence Reporting for SAP ERP [original link is broken] .Note this is prototype not a product) and fetch your CRM data also in the virtual tables of the DF. Still you have to rebuild your hierarchies manually in the universe.

Data Federator ODS Problem

Hi All,
I´m building a scenario in SAP BO Data Federator where we connect to a table in BW (ODS) and with a jdbc connector we get the data to build a universe in UniDesigner.
The problem is that the data returned by data federator doesnt match the data in BW, we always get less records in Data Federator when we perfom the query in data federator query tool.
Can anyone give a clue whats happening and where to start looking? we already did a trace in BW (ST05) and the SQL statement seems to be right.
thanks,
Pedro

Hi,
I had the same ODS error when generating the databasis.
This error we have been solved now.
But do you know how to correct the following error:
For Goodwill Data two indices are created which are completely identical. This leads to an error. How to solve this problem?
Thanks for brief feedback.

Data Federator not fetching data USING Netweaver BI Connector

Hi Gurus,
We have upgraded the BW system to use the Data federator.
callback ID that SAP NetWeaver BI uses to contact Data Federator has been configured as mentioned in guide.
we have already configured the CONNECTOR and we are able to test the connection in DF Designer and the connection is successful. i am able to see the list of fact tables and i am saving the data source and making it final and deployying my project .
i am using the jdbc connection and data federator strategy and the strategy is also creating the joins and classed automatically. when i export my universe and try to create the webintelligence report i am unable to see the data .even when i execute with one object and one keyfigure it is same .
even when i test my data source in designer to view the data using query tester tool it is also not able show the data it takes huge time and no data getting retrieved .
i would appreciate if you could help me with this issue
Regards and thanks

Hi,
Which version of Data Federator are you using ? Direct access to ECC table is not yet supported using Data Federator.

Data Federator Steps

Hi,
I need some help in Data Federator. How to create Projects etc and connections?
What are the steps and how does it work with InfoView, WebI and Universe?
I will appreciate steps and charts besides guides.
Thanks
Bashir Awan

7.created a calculated KF in the BW query and want it added to the universeu2026steps to transport the same
You will need to refresh the universe in Designer.
You can then transport the universe using LCM.
