Master Data modeling with data from several source clients

Hi people,
We have a modeling issue at hand..
From several R/3 sources, separated as Clients (eg. client 100, 101, 102 etc.) we will load data (transactional and Master Data) to one BW system.
Now, I am wondering what is the best way to avoid Master Data issues here, when data can be different for the same objects in the various source systems (clients)
Example:
In source client 100, 0MATERIAL 1000 = PLASTIC
In source client 101, 0MATERIAL 1000 = WOOD
I have tried to understand how compounding with 0SOURCESYSTEM works, but I can't see how that will work for us, since we may have several clients on the same sourcesystem (e.g. client 100 and 101 can be on the same system). This would not help me separate the masterdata.
- Does anyone have experience with this they could share?
- Is it a possibility to add 0LOGSYS or something to our InfoObjects that we will load?
- Do we then add the InfoObject to the cube in the end?
Any inputs that can clarify this is appreciated. Points awarded ofcourse!
Cheers,
Jon A.

Hi,
Donot go with one server to define it as a source system .I mean ,Even though you have only one R/3 server . you have 3 clients in it. So go with Clients to define the source systems.
So in BIW You must have 3 different source systems in Source system tree. Am I irght?
So all of them has different logical system names.
So use 0LOGSYS as compounding characterstic.

Copy data models and reports from BW 3.1 to NW 2004s

Hi experts,
Our client has two BW servers: BW 3.1 and BI 7. BW 3.1 contains lots of data models and reports. And the BI 7 server is newly installed.
Now we want to copy these data models and reports from BW 3.1 to the new BI 7 server. Are there any solutions for this?
Thank you very much in advance.

Hi Frank,
Sounds like a cross version transport is needed.
This is a solution we have used to do what you want to do:-
Create and release a transport as per normal.
Copy and transport the files from the source system (BW 3.1) e.g /usr/sap/trans/data & /usr/sap/trans/cofiles to the same folders on the target system.
Basis help is needed here.
From here onwards using stms_import should help you in the normal manner.
Works a treat.
Have transported the following all correctly appearing as 3.x data models in NW2004s.
DSO objects.
Cubes
Transfer/Update rules
Reports.
Cheers,
Pom

Filling bc travel data model with test data

Hey i read somewhere that there is a app to fill the bc travel data model with test data.I been searching but havent found one in the preview version.Please help me if anyone knows how to get it done.Filling it manually is taking a whole lot of time.

Go to the ABAP Editor (SE38) and execute the SAPBC_DATA_GENERATOR program. This program generates suitable sample data in the tables of the flight data application.

How to share JHS BC4J data model with JClient application ?

In our project, some application system using JHS Struts/JSP solution but others which need rich UI application prepare to adapt JClient solution, so whether we can share JHS BC4J data model with JClient application ?

Ting Rung,
The JClient application will communicate with your application module. So all logic in you app module, EO's and VO's can be resued by JClient. Logic in Jheadstart handlers cannot be reused.

Data Models and Data Flow diagrams.

Hi Gurus,
Can anybody brief me the concept of Data Models and Data Flow Diagrams and their development with illustrations. And is it a responsibility of a Technical or a Functional consultant..i.e to translate Business requirements and functional specifications into technical specifications, data flow diagrams and data models.
Your valuable answers will be rewarded.
Thanks in advance.

Hi,
Concept of Data Models
Data model or Data modelling is basically how you define or design your BW Architecture based on Business requirements. It deals with designing and creating a effcient BW architecture sticking to standard practices.

Right click on the data target > show data flow .
It shows all the intermdeiate layer through which data comes into that particular object.

This is done genrally in the designing phase itself by a Senior Technical Consultant with the help of a Functional consultant or a Techno=Functional consultant interacting with Business.
Hope this helps.

Differences between operational systems data modeling and data warehouse da

Hello Everyone,
Can anybody help me understand the differences between operational systems data modeling and data warehouse data modeling>
Thanks

Hello A S!
What you mean is the difference between modelling after normal form like in operational systems (OLTP) e. g. 3NF and modelling a InfoCube in a data warehouse (OLAP)?
While in a OLTP you want to have data tables free of redundance and ready for transactions meaning writing and reading few records often, in an OLAP-system you need to read a lot of data for every query you do on a database. Often in an OLAP-system you aggregate these amounts of data.
Therefore you use another principle for these database scheme. This is called star schema. This means that you have one central table (called fact table) which holds the key figures and have keys to another tables with characteristics. These other tables are called dimension tables. They hold combinations of the characteristics. Normally you design it that your dimensions are small, so the access on the data is more efficent.
the star scheme in SAP BI is a little more complex than explained here but it follows the same concept.

Peter

Thanks again. I tried channel 13 and it seemed to work better, with less dropouts (albeit not perfect) but sadly my slightly ageing laptop wouldn't recognise the network at all with the Hub set to that channel, so I had to switch it back to 11!
Will try the factory reset at some point to see if that improves things.
I have the same issue with my iPad when streaming videos...like the issue posted on ‎25-04-2014 18h36 by Steve.

I was infact planning to change the iPad or sell it off due to this recurring problem.

Can I pass parameters from a dashboard via a dashboard prompt and presentation variable to publisher report based on a data model with select statements in OBIEE 11g ?

I have a publisher 11g (v 11.1.1.7) report with a single parameter. The report is based on a data model not a subject area. I created a dashboard put a dashboard prompt and link to the report in separate section on the same page. The dashboard prompt sets a presentation variable named the same as the parameter in the report.
The problem was when I created the dashboard prompt, it forced me to select a subject area which I did (though did not want to) and then I created both a column and variable prompts. But clicking on the
report link completely ignored the value that I thought would be passed in the presentation variable to the report.
Side note : My report uses a pdf template for its layout where I have mapped the columns names from my data model to the form fields on the pdf form. I noticed that if I create a publisher report based on a subject area, then I do not have the choice to choose a PDF as a template type for my layout. (I only see BI Publisher Template as a choice).
I see some documentation online that suggest it could be done in 10g.
Thanks
M. Jamal

Ok,
I just tried that and it still doesn't pass anything to the prompt.
I changed the prompt to an edit field and I made the following weblink but when i click the link from an account it doesn't put anything in the prompt and all data for all accounts is shown.
This is the URL maybe I messed something up...

Filtering multiple-XML data model with parameters

I have a data model that consists of a concatenation of 9 separate RSS feeds (weather information from 9 different cities coming from http://www.weather.gov/data/current_obs/????.xml, where ???? is the National Weather Service station ID). All of the feeds have exactly the same format. When I view the raw XML data, I see 9 different values of station_id and of every other tag. So the XML data looks fine. Now I'd like to be able to select one city at a time in an LOV dropdown.
I've created a static LOV called Cities with the list of the 9 station ID's. I've created a parameter called city that is tied to that LOV.
What I can't figure out is how to tie the selected city to the station_id field in the concatenated XML dataset.
I've tied adding a parameter to each rss data set, entering each city's 4-character station ID into its Parameter Name field, and of course choosing city as the parameter. For example, the Parameters section for the Amarillo rss feed would show a Name of KAMA and a Value (Parameter) of city. While this seems logical, selecting the parameter on the View screen doesn't change the display.
Is there a way to accomplish this?

Ahhh, post as in "e-mail". DOH!

Publish data model with designer

Hi,
so far I used ERwin for data modelling. ERwin can generate HTML output consisting of the graphical data model plus hyperlinks on the tables. If you click on a table a report pops up with all details, e.g. table and column comments.
I find this very useful to publish the data model.
Is there something similar available with Oracle Designer?
I found this announcement, but no product: http://otn.oracle.com/products/designer/pdf/ROB_Announce.pdf
Best Regards,
Jens

If you have any recent release of Designer installed, then you have the ROB automatically installed. Select your Start menu in Windows and then navigate through your menus to the Designer sub menu and you'll see a link for setting up the ROB.
The ROB was made available as part of Designer from March 2003. The lastest release of Designer, viz Designer 10g (9.0.4.4) and the equivalent 9i and 6i releases, all now avialable on OTN, have additional support for the ROB. This offers the ability to save and ERD or Server Model Diagram directly to the ROB.
You do need to add the "hotpost" functionality manually. The ROB help gives a step by step apporach on adding these hotspots. There are a number of demos on the Designer demo page on using the ROB and configuring the App Server to use it. http://otn.oracle.com/products/designer/demos.htm

Needed SAP CRM Data model with Object, Entity and Attribute level details

Hello all,
We are working on a huge IS-U / CRM implementation and we are still in the data gathering phase. The client has a whole load of legacy systems that will be replaced with IS-U and CRM. Right now we are in the process of developing data models using Excel first and then presenting them to the client to go forward from there. For this we need to have all the business objects, entities and their attributes.
I know about the SD11 transaction, but we don't have a CRM system yet. My colleagues have access to a German ERP system and they were able to get models for HR, FI and Asset management. I tried for the Business partner / customer in there, but the models were not proper.
So, once again, I need the specific data models out of SD 11 for CRM business partner. If anybody has the information, please do pass it on to me as I need them urgently. It would be a great help if somebody can do so.
Regards
Rajesh

I suggest the following:
Please, check whether the system works if you activate the implementation BUPA_F4_AUGRP.
In addition check the notes 559662, 674869 and 782927. Maybe the notes are already implemented but you can try then the implementation of the BADI (SE19). It should resolve your issue.
I have implemented this Badi solution before, and after activation; the search help ; nor search result list did NOT show any Business partners anymore that had an authorization group I was not allowed to see.
kind regards

Power Pivot Data Model with Linked Table

Can anyone provide me with some suggestions as to how to accomplish the following in Power Pivot?
I have the following Pivot Table fields. I'm trying to create a data model to allow me to filter all of the projects by the selected Fiscal Year. The Fiscal Year table is a dimension I created to group the data by.
I'm considering separating Projects into multiple tables such that 1 table is for Year1 information, another table is for Year2 information (includes Year2FiscalYear, Year2BudgetCAP, etc.).
I think what I need to do is create a measure to allow me to filter the records by fiscal year. Anyone have any ideas?
Thanks,
Roland

Hi Greg,
The data is coming from Project Online (OData feed) and SharePoint lists (all within Project Online). I'm creating an Excel Report.
The reason I can't use Power Query is because refreshing a report that is built using Power Query is not supported via browser. Power BI is needed to do this. On the other hand if I build an excel report using Power Pivot only, the browser refresh functionality
works.
The Year1FiscalYear, Year2FiscalYear, etc. are all enterprise custom fields in Project Online. Therefore I have some control in being able to change the format of the data. I'm looking into what are some options on my side to configure Project Online or
SharePoint lists to make building the model simpler...
Thanks,
Roland

Decision to Build BW data model with legacy data

Hi experts,
I was assigned a task to take decision on creating new data warehouse on the following scenario's
Option1:
1.SAP BW + Legacy data( Separate database)
Option2:
2.SAP BW+ Legacy data integrate to BW.
Please let me the pros and cons involved in integrating legacy data to BW or to report separately as two different data bases using BOBJ.Client is having SAP R/3 EEC6.0 running.SAP data is around 60% and remaining is legacy.
My question is which option is better with some detail.
Regards
prasad

Hi Prasad,
As mentioned no need to combine Legasy data and BW data in BOBJ.You can directly extract to BI from R/3 and Legasy Data.But
Please check the folliwng points from DB People.
1. As per requirement how many Tables that you are using to extract the data?
2. You have three source tables.But there are no unique records.In this case first you need to identify the common key field.
Note : That key field also should same as in R/3 also.
Based on the three source tables inform the DB team Mainatain a separate table (Which should collect only common record from three tables).
3. Now you can load the data into BI.So the above scenario will resolve issue.
Issues & Concern :
1. If yopu extract Lagasy and BI to BOBJ ?How u r going to combine data in BOBJ to generate a global report.
2. Is this possible to maintain a separate table in DB by the DB team.
Check once with DB team before proceeding further.
Regards
Ram.

Data model with a dynamic table name

Hi,
I have report requirement, where in the table name in the data model query is unknown.So I use lexical parameter like " select * from &P_TABLE_NAME". This dynamic table is created and data populated in the before report trigger and table name is assigned to P_TABLE_NAME. The parameter P_TABLE_NAME has to be assigned an initial value otherwise the report errors with 'invalid table name' error. So I give a dummy table say 'DUMMY' as the initial value which has the same structure (with no data ) as the table that is being created in the before report trigger.
The problem is that the data model query is being parsed ( and maybe executed ) even before the 'before report' trigger is run. As a result, the report o/p is empty, since the query used the DUMMY table for execution. But after the report completes, I can see the dynamic table being created with data.
Question: Why is the before report trigger getting executed after the datamodel query is parsed and executed.
Regards,
Suresh

Hi....
yes, these are the settings I have:
server folder: /Applications/MAMP/htdocs/dwphpelclasico
web url: http://localhost/dwphpelclasico/
They should be correct. But I still get the message:
Warning: require_once(Connections/elclasico.php) [function.require-once]: failed to open stream: No such file or directory in /Applications/MAMP/htdocs/dwphpelclasico/list.php on line 1
Could it be something with list.php?
This is a new file I created to display my tableand where I am inserted the record set.
thanks
