BW 7.30: Modeling integration between SAP Business Objects Data Services and BW | Part 1 of 2 – Connect Source System

With SAP Business Objects Data Services, there are around 22 different adapters to external systems available. However using them in BW was a quite clumsy task, especially if   you are a BW modeler and not so much of a Data Services crack.

With BW 7.30 and Data Services XI 4.0 there is now a modeling integration, where you do not need to leave BW Data Warehousing Workbench at all in order to connect to any of   these external systems and get the data out!

But of course, since Data Services still is a separate installation, there are some prerequisites, which you need to do on data services in order to be able to retrieve remote   function calls from your BW system. Let me fly through them quickly, before I describe the actual modeling integration based on this RFC connection.

Open up the Data Services Management Console,


Windows Menu to start DS Console



DS Console Logon


Log in and go to the Administrator Section. What you need first and foremost, is an SAP connection, i.e. an RFC server listening to BW:


RFC server list


In my screenshot, there are already quite some Servers configured, initially, this tab is empty. So go to the “RFC Server Interface Configuration” Tab and add one:


RFC server creation screen


The type of connection on ABAP side is a “registered server program” and the logon data you enter here is needed to register this program on the SAP application server. For that   reason, you need a separate RFC server configuration per SAP application server in data services. Give them all the same “RFC ProgramID” and remember it. I called mine   “DI_GEMINI”. You will need it later when you do the inverse connection from BW to Data Services. You may also maintain the SNC settings in order to secure the connection between   BW and the Data Services system and enable logon check when a BW user calls up a function in Data Services. For this, you need also to set up the BOE CMC user configurations,   but it would go beyond the scope of this blog to describe this in detail.

Going back to the Status tab, you find a stopped instance, which you start:


RFC server instance status: stopped


Now Data Services is able to receive RFC calls from BW.

Now, all basic configuration has been done, we finally can enter BW data warehousing workbench and start connecting our external system (in my example, I have a MySQL DataBase).   Start with the source system area of data warehousing workbench:


BW Data Warehousing Workbench Source system tree


Let’s create one:


Source system creation screen: Enter Name


Now you would expect to enter something like “Data Services System”. But no – you do not want to connect to Data Services, do you? You want to connect to your MySQL-Database   where your business data is, isn’t it? So let’s call the source system SALESDB resp. “Sales Database”, because I have stored sales data in my external database.

Next, you are thrown to the RFC connection screen:


Transaction SM59: TCPIP-Destination creation


Here you enter the RFC program ID, which you had named your RFC servers, we had called it DI_GEMINI, remember?  If you did maintain the SNC settings in the RFC server, switch to the “Logon & Security” tab and check the radiobutton “Send Logon Ticket without Ref. to a target system”:


Transaction SM59: TCPIP-Destination security settings


Save, test and leave the screen.

Following will pop up:


Source system creation screen: SBOP source system details


Now this screen needs some explanation, since now, unfortunately but unavoidable, the terminology of data services and BW both jump at you. The first two fields are still quite   straightforward; you need to enter the name of the repository of your data services system. You may use the value help to do so, which goes RFC to the data services system to   retrieve the information. Same with the Job Server. 


Value help for repository and job server


The second frame on the attributes popup is about sending the data from data services to BW. Data services uses an object called “data store” to define the target of data. It   has absolutely nothing to do with the BW object DataStore or DSO. The data services term sometimes has a tiny space between “data” and “store”, sometimes the “Store” is not   capitalized in “Datastore” 😉  Ok, in order for us to define such a data store, we need the user and password to logon to the BW when sending the data – all other information like host and client the system   knows itself since we are currently logged on to this machine. We should use the BW background user BWREMOTE or ALEREMOTE or however you called it here.

The third frame on the attributes popup is the most complex one, even though it has only one field… In order to access the business data on my MySQL database, I have to define   yet another data store – remember we access it via data services. This time it is a source data store (a data store might be source or target). Also here there is a value help:


Value help for Data Services Data Store


Now in our case, there is no data store yet available which connects to the MySQL database where my data is. So I enter a new name like SalesDatabase into the input field and   press the “create” button. Now the complexity overwhelms:


Value help for Data Store Type


Obviously, the system is asking me, which type of data store I want to create. MySQL is a database. More exactly, it is a relational database management system without change   delta capture. So let’s pick “RDBMSDataStore”, but not “CDCRDBMSDataStore”. Who, why are these terms so crude and no explanation? I am sorry, but the reason is, we are composing   an XML message here – these names are XML tags defined by the set of XSD files which data services publishes to describe all kind of data stores. The popup is generically   generated from parsing these XSDs. The good thing about this is, that by thisthe popup is always up do date with the data store definition offered by the corresponding data   services installation, if it offers a new type of data store, which is not known today, it will automatically be available also in BW. The bad thing is that there is some user   guidance missing, like explanations or some value helps.


Data Store Creation


A new input field in the name column pops up, the “configuration”. A data store in data services may have different configurations, each connecting to a different system. We   only need one configuration and it is automatically named DEFAULT. But the type of configuration we need to choose with the value help:


Data Store Configuration Value Help


And there it is – MySQLDataStoreConfiguration! These two popups give you an impression on the variety of source technologies which data services is able to connect to. Let’s   pick ours.


Data Store Creation


This is now the complete XML defining the data store – we “just” need to fill in the values. Luckily, there are value helps (enumerations) for most of the fields, like Version –   but unluckily not for “DataSource”.

DataSource!? No, not what you think. Again, this term here has absolutely nothing to do with the BW DataSource. What is meant is the ODBC-Datasource, because MySQL database is   accessed via ODBC technology. We enter the name of the database: SALESDB.

Then we need user and password to connect to the database. For entering the password, we click on the input field and obtain another popup where we can enter the password   invisibly:


Password input popup


This is the last input we need, let’s confirm all popups and the system will go to data services and create the two mentioned data stores and store their names and the name of   the repository and job server as attributes of the source system in BW. The data store configuration itself will not be stored in BW – but you can change it by clicking on the   edit button in the source system attributes, it then will be retrieved from data services:


Source system context menu



Source system detail: Data Store Edit Button


Stay tuned for the second part of this blog, which shows how to actually access a particular table in our MySQL database!

      your bolg seems to be single source of information for connecting SAP BW 7.3 with BODS. i m using BODS XI 3.2 version. but when i m trying to connect it through DataServices(BOBJDS)Connection from RSA1, i m getting RFC error at last.but my connection test is working fine. when i m coming out from that screen it is asking me for Attributes of BO Data Services.
      as far i know i entering correct values in the fields, but at last it is throwing 'Error in Remote Call of Destination, and later in the description saying 'handler for RSBOBJDS_DATASTORE_GET_LIST was not in stalled'
      can u help me out over this. my support pack is 01 for BW 7.3.
      can u help me out.

      The feature requires Data Services XI 4.0 or higher. Sorry that I did not mention this in the blog.

      hi thomas,
      thanks a lot for your quick reply.
      so does it mean that we can connect BW 7.3 with BODS X1 3.2 only through External Systems (PARTNERS). because through External System i am able to create a connection and run the job in a similar way as of 7.2.
      can u help me out?

      Yes, the XI 3.2 can be connected as "3d-Party" system rather than as "Data Services" system.
      You are able, however, to already use the BW 7.x DataSource (RSDS) in addition to the well-known BW 3.x DataSource (ISFS) technology for this 3d-Party system.

      Sounds like an installation issue with Data Services. Please create an SAP customer message for the Data Services Team.

      Hi Thomas,

      this blog seems great to me, but I cant see all the images. Is there any way to get the complete view.

      Best regards, Josko.

      Hi Thomas,

      How do you choose what repository to use on the data services side? I'm working in a multi user environment and someone mentioned there had to be a connection per local repository for each user. This doesn't sound right to me but there isn't any information about this anywhere else in the documentation.
