Creating DataMarts in BI 7.0
Hi,
If I have to load the data from the Data Source to the InfoCube, then the procedure of creating the data marts for the Data Source still exist in BI 7.0 or is there any other process to do that.
Can any one please explain me with the detailed steps, about how to load the data from the ODS in to the Info Cubes.
Thanks, I will assign the points.
Do I have to create the Transformation too between the InfoCube and the ODS?
Thanks for the info, I have already assinged you the points.

Is Business Objects is ROLAP tool?? If access datamart performance Decrease
Hi Bo gurus,
i am getting good response from u guys.And keeping improving myself through SDN community.And i came with a different question as follows,
we have created datamart from the database,it does not have physical existence.we have created the target tables using data integrator.
Now we use BOXI R3.1 ,created the universe according to the business and generated the reports and dashboards from the datamart.Now whats the problem we are facing is that for generating reports in voyager we short fall of OLAP cube.As voyager can only access OLAP cube not the universe directly like reports.
Now the client have asked why we have not developed the datamart in OLAP cubes.But i replied that for creating universe there is no need of OLAP by using the datamart target tables itself we can create universe and generate reports.
But client says why u have not created in OLAP cube.If i also create which is best method to implement whether MOLAP or ROLAP is best ???
I am trying to convince that ROLAP is best as it can handel large database.
But client is saying if we implement MOLAP performance will be faster....
I have question whether creating universe on the top of OLAP will be faster and make some difference or directly from target tables(datamart-facts & dimension) itself work fine????
I have gone through some of sites telling that Bo is ROLAP tool icon_confused.gif and Cognous is ROLAP tool is that true.....
PLZ Give me some suggestion icon_idea.gif on this....
Thanks in advance GURUS,
santoseHi,
i would recommend posting this in the "Enterprise Information Management" Forum. DataServices belongs to the EIM productline of SAPBOBJ and there are the pros for the Tool.

thank's
aamirYou need to have the enterprise version of Oracle DB 9.2.0.2 in order to have DM4J to work fully. It will run on Oracle DB 9.2.0.1 but you would need to install a JMS patch to have the components run successfully. This is better done by just upgrading to 9.2.0.2.
If you have the correct DB then you need to establish a connection to the db using the "ODM" account and password. You can not access data mining in the db other then through this account.
Additionally, all ODM_MTR tables are granted to ODM for access out of the box. If you want more data accessible to ODM you will need to grant these individually. -
Datamart works for Compressed data
Hello
We created Datamart for the Billing Cube and needs to send the data to New Billing Cube.
I question like for the Old Cube for which Datamart is created, got some compressed records.
So when iam loading the data from Datamart to new cube, will it be possible for me to get the compressed records too.
Do we need to load differently for compressed records.
Please provide some solution if anyone has faced this, it will be very helpful for me.
Thanks in advanceHello,
when you load data from one cube to another, all records will be passed; compressed and not compressed.
Furthermore, if you are creating a new cube and need to load all the data from the old cube to the new cube, I recommend to compress the old cube fully, update indexes, and create statistics on it; the selection and fetching of data will be faster.
Hope this helps...

Can MultiProviders , Remote Cubes Support Datamarts Concept?
Hi..
Can some body tell me if we can generate export datasource on a Multi Provider? also, can we include one multiprovider or remote cube in another multiprovider as one of the objects?
thanks..
kishoreKishore,
No we cant create DataMarts on Multiproviders and Remote cubes, because these are the pipeline, they will have only the structure not the data.
Question 2.
can we include one multiprovider or remote cube in another multiprovider as one of the objects?
No, you will not get any option,because same what I mentioned above.
Thanks

Creation of export datasource failed
Hi All.
i copied a bussiness content data source object (DSO) and tried to activate it. it is giving error that
"The creation of the export DataSource failed"
Why ??? where m i going wrong.
Thanks & Regards,
MoHello,
This is the problem becos the system is unable to create DATAMART for DSO object. The following reasons might be hindering the creation of DSO. Please check whether
1) You have proper authorization to create Datasource/Datamarts.
2) If so then, check whether DATAMART for the BW Self Source System is properly Installed from Business Content. (I hope you are working on the version 3.5 or later.. here we need to manually install Aplication Component related to Datamart from Business Content so that Datamart creation never fails after that)
3) Also check BW Self Source System is properly functioning.
Thanks

Help Required: Working with relational data
Hi,
I'm looking for some advice
Scenario
We have a customer who has an SE relational database with Apex for transaction processing. They require reporting functionality and are debating whether to buy BI SE One or BI EE; they will not buy the enteprise edition database though.
Questions
Here are my questions:
1. In order to use answers and dashboards, does the relational data have to be in a dimensional format. Is this reccommended.
2. We were debating on whether to create data marts for various business requirements. Is this standard procedure for relational data (Which is not too complex)
3. If the data has to be in a dimensional format, is this best modelled using warehouse builder or the model layer of the repository using BI Administrator. (Baring in mind that the customer is an SME using a SE database)
The main problem where having, been fairly new to warehouse building, is that we dont know what the best path is to take when working with relational data. Do we create dimensional models? What should we use? Is a relational structure suitable enough?
Can anyone shed light on our problems
Regards
Kevin1. In order to use Answers and Dashboards you do not need to have a Data Warehouse. It can report out of both Transactional database as well as a data warehouse.
2. It depends on what your business requirements are. BI EE/SE1 does not require you to have data marts. Data Marts would give performance gains, would help you in visualizing the transactional data from a business standpoint, is a big plus but not a mandate. If you want to go that route of creating Datamarts, you can easily do that using BI SE1 since that gives you warehouse builder which can be both used as a data modelling tool and a ETL tool.
3. Warehouse Builder is a ETL tool. It helps in you visualizing/deploying data warehouses in databases. But BI EE Admin tool is more of a logical dimension modelling tool wherein the facts and dimensions do not exist physically but the tool uses them to do the querying/processing.
Since you are just starting, what you can do is to use BI EE directly on top of the transactional system for the time being. But as a long term solution you can start working on your data marts and as soon as they are ready you can port the BI EE on top of them rather than the transactional system.

Hi Experts,
I have a requirement where I need to connect the existing BI system to the new proposed BI system. I am told about the open hub services. But i believe there could be a better way of doing. Can you help me how to connect existing BI system to newly proposed BI system.
Regards.
PrasadHi Prasad,
You can create datamarts from exisitng system and use thse datamarts to load to new Bi System from existn system.
1) You can have a RFC Connection between existing BI System to New BI System.
2) In the exisitng system , suppose you want the data of a cube from exisiting system to new system. Then cl ick on the cube and additioanl function --> Export datasource. This will be created with a datasource (8*) * - cube name
3) Once the RFC connection is established, go to new BI System and then in Source Systems , you will find the old BI System source system also. Then replicate the datasource.
4) Create transformations,dtp from this datasource ( which is datamart and which will provide the data from old system).
Hope this helps.
Thanks

Query to conbine 2 lines from table
Hi all
I have a problem in constructing sql query to combine 2 lines from table in Oracle 11g database.
I will explain, i have one table containing call transactions loaded in one table from 2 different sources, one is from IN which is tagged IN and the other from MSC which is tagged MSC. One subscriber call is registered in IN and MSC and loaded in the table. The problem is the data from IN contains the call duration but not contains Cell information. I'm creating datamart to combine the two lines in one lines but i don't know how to do from query.
Here is an overview if my data:
Source Orig Dest startdate cellid duration
MSC 550000 220000 15/05/2012 02:03:29 235e
IN 550000 220000 15/05/2012 02:03:30 10
MSC 550000 220000 15/05/2012 02:04:00 235e
IN 550000 220000 15/05/2012 02:03:59 15
MSC 550000 220001 15/05/2012 02:06:18 235f
IN 550000 220001 15/05/2012 02:06:18 60
The line i want to have is for each line of IN source i sjhould have the cellid like below:
IN 550000 220000 15/05/2012 02:03:30 235e 10
IN 550000 220000 15/05/2012 02:03:59 235e 15
IN 550000 220001 15/05/2012 02:06:18 235f 60
The query should linked by Orig, Dest and date but for some rows there are difference in seconds.
Please help.

Is that supposed to be another INSERT statement?
Test your code and, if necessary, correct it before you post it.
Is that sample data supposed to produce the results you posted originally?
If so, explain, step by step, ho9w you get them.
If not, post the results you want from that smaple data, formatted, between \ tags, as explained in the forum FAQ {message:id=9360002}
In my orioginal message, I said "ORDER BY" where I meant "GROUP BY". If you change that, and use your new table and column names, does the query I posted earlier do what you want? If not, point out where it is wrong, and show how you might get the right results in those places. -
Steps too create connection between OBIEE and Datamart on UNIX box..

How to create a datamart from cube
Hi All,
I want to create a data mart load from one cube to another cube how to do it what all are the steps need for it.I know in ODS we have a setting call update to further data target of we mark it it will create a data mart.
bwuserHi,
Please right click on the cube to generate export data source.
A 8 data source will be generated. You will then be able too use this to load the data to other data targets,

Thanks in advance

sunilHi Sunil,
Your problem Subject and Description doesnot match. If you need to transfer your RPD from Windows to Unix, here are the steps. In fact there is nothing complicated involved.
Hope you have OBI already installed in the Unix machine,
1. Ftp your RPD from Windows machine to the Unix server.
2. Put it in the $SAROOTDIR/server/Repository path
3. Make changes in the NQSConfig.ini file, if needed
4. Bounce the OBI Admin service
But if you need to change the connection pool details on Unix, that is another story altogether.

Cube to cube datamart in 3.5
I have built a cube to cube datamart and cannot determine how to initiate the load. When building a datamart with an ODS as the source, it is quite obvious (right-click ODS and select Update ODS Data in Data Target). However, this option does not exist in the case of a cube.
It's a one-time load of some historical data. I don't require scheduling of deltas. Just a single full load.I do however need selectability on a date field to exclude recent data.
Can someone please advise how to initiate this data load?
Many thanks,
BrettHi,
Go to the infosource tab in the RSA1 and search for 8(your infocube technical name).
Eg: if your source infocube 0tct_01 then search for 80tct_c01.
Create an infopackage on the 8.* ICtechnical name and schedule the load. This will load data from your source IC to Target IC.
If it is not clear please let me know.
Thanks

Database Development and Creating Objects in the Enterprise
Hello Everyone,
I have found myself filling the role of DB Developer for a DataMart project in a large enterprise. We are looking at replicating and consolidating multiple schemas in near real-time into an ODS for Reporting and Data Integration purposes. I did a POC locally in DEV to create Materialized Views for this purpose. It seems to work fine, I've got them on Fast Refresh, added a unique identifier etc.
The DBA stated I was granted the Priv to create the MVIEWS bc our vendor requires more PRIVS than is normally allowed for other apps in the Enterprise and it was only done on our server. Now I requested to try the same thing, however on the remote ODS DB over DBLinks. He stated creating objects on the ODS is a 'bad idea' and not allowed without engaging the broader DB group, even for DEv purposes. He also stated that MOST enterprises don't allow creating objects, and only allow DML. Problem is, once we engage that group it could add significant time and money to the project. Which seems silly as I just want to see if it's a feasible option.
Any thoughts on this? Can anyone share experiences regarding what is and is not allowed at the DB level strictly for DEV purposes and not on PROD?
Thanks,
PRAJNAThanks for the input jgarry. It does seem they are treating DEV like PROD in this case. Which has the potential to hamper innovation and new ways of doing things, especially in an aging IT environment where we might be stuck in our ways of doing things. It also sounds a bit general and not necessarily the case that 'most companies also don't allow this sort of thing'. I haven't worked in enough shops to say one way or the other however.
Yes, creating a local DBLink would be an option, but I wanted to test this method running across two physical servers ideally. Worth a try though. -
Design Steps for logical modeling of Dimensional DataMart
Hi
begin to understand the process off building
a Data warehouse off of an OLTP database. So thought I would put down the steps
involved (as I understand them) for clarity. Dose this look right? is there anything im missing?
Step 1 - Determine the dimensions
create a
business matrix that identifies the dimension and there relations with each
other
Step 2 - Detarmine the measures
set out the numeric
values required for analysis
Step 3 - Determine the dimensions
attributes
identify elements that would be used to filter or group data
for analysis
Step 4 - Create a Data map
map out source and
destination columns between the OLTP source and each dimension and facts
table
Step 5 - Include a Date dimension
almost every datamart
has one this can be scripted
any advice welcome.
thanksHi Slihp!
Beside Leo N's answer which is correct, I would modify step 4 a bit to add some general info on how the data will be cleansed, if needed, during the mapping process (usually done with the help of SSIS).
And since you have received three useful links, I will add another one which will be of help to you: Delivering
Business Intelligence with Microsoft SQL Server 2012 - a very good beginners book which walks you through all the steps of building a data warehouse.
Regards and have fun :),
