In this document (my first one) I will comment how to create a connection from SAP BW to SQL Server step by step and the small problems that I encountered during the process. I hope it can help to someone who has to perform this process in the future.

Step 1. Create the Source System.

RSA1 --> Source Systems --> Right click on “DB Connect” --> Create…

Step 2. We need to fill the next fields:

Logical System Name: in our case we have named “MSSQLS”.

Source System Name: Text field (40 Characters Long).

Type and release: here we can specify a type and a release of this source system.

Step 3. Once named the system we have to create the connection parameters:

DB Connection: the logical name with which we have created our connection.

DBMS: the database type to which you want to connect. In this case “MSS”. There are the following ones:

User Name and DB Password: user and password with which we are going to connect to the database.

Conn. Info: specific information for database connection. In our case:

MSSQL_SERVER=SERVERNAME1 MSSQL_DBNAME=DBNAME1 OBJECT_SOURCE=SAP

With:

MSSQL_SERVER: name of the server we are going to connect.

MSSQL_DBNAME: name of the database from which we will extract data.

OBJECT_SOURCE: name of the schema in which the tables are available.

Permanent: related to what happens when an open database connection is lost due to a database failure or lost network connection.

Connection Limit: Maximum Number of DB Connections

Optimum Conns: Optimal number of DB Connections

Step 4. In SQL Server the user must have the following permissions:

Step 5. We check that the connection is correct.

Step 6. We select the tables or views from which we want to extract the information.

Right-click --> Additional Functions --> Select Database Tables (3.x)

Then we press “Execute”:

The following tables and views have been found:

... the same views we wanted to access:

Important note: as seen in the image below, we cannot access "View_2" because the names of the tables/views (and their fields) must be in UPPERCASE.

Step 7. If we select any of the first four tables and we press "Edit DataSource" we can see the fields (Field Name, Database Type, Length in Database ...) of each table:

Step 8. If we press “Display Table Contents”   we can see the content:

Step 9. If we press "Check DataSource"   we can verify the DataSource. In this case displays a warning because the length of one of the fields is larger than 16:

Step 10. And if we press “Generate DataSource”   we create the DataSource in BW side.

A message shows that the DataSource (6DB_tablename) has been successfully generated:

Step 11. If we return to the Workbench we can see that our DataSource has been generated (in version 3.x):

Step 12. Click the right mouse button and migrate the DataSource to version 7.0.

Step 13. Create the transformation rules (as we can see below):

Step 14. Create the Infopackage and DTP.

Step 15. Execute the Infopackage and DTP and we can see that our Infoobject (ZCCAA2) has been loaded correctly:

Good post - You may want to mention that MSSQL only works if your SAP BW system is installed on a Windows Server or Linux OS.  If you are UNIX, this won't work

Hi Carlos,

 

Thanks for this article.
I have tried to connect to BW with SQL Server 2008.
I am getting an error while creating the source system :

 

"No shared library found for the database with ID MSSQL"

 

Here MSSQL - Source system name that I have given.
Am I missing something ?


Please help me.

 

 

 

Thanks,
Jay.

Hi Carlos,


Thank you so much.
I have used MS SQL and unfortunately, Application Server OS is Linux and DB is Oracle.
With your answer, it makes lots of sense 🙂 Let me try with Oracle DB connection.

 

Thank you so much Carlos.. You are genius 🙂

 

 

Thanks,
Jay.

Can anyone let me know if this functionality has been removed?

My DBCO connection is set-up and as far as I can tell, using check, it is succesfully connected? However the Additional Function > Select Database Table (3.x) path does not exist on my context menu. as per scren shot below.

Hi Gareth,

 

The functionality has not been removed. Please, review the connection info (MSSQL_SERVER MSSQL_DBNAME OBJECT_SOURCE) and make sure that the user has enough permissions in both SQL Server and BW systems.

Carlos

Hey Carlos

 

Thanks for your response...Im going to try be a bit more specific. And I am new to this so apologies if this is a bit poor.

 

SAP BW version is 7.4

 

MSS user ID is uppercase and this user has permissions to all tables and views in the server instance.

 

MSS connection string is accurate as far as I and the MSS DBA can confirm.

 

The only area that you are giving me some doubt is the BW system permissions. Please could you elaborate on these.

 

Kind regards

Gareth

Hi Gareth,

 

 

 

Don't worry, I will try to help in anyway I can. What roles and authorizations has your BW user (t-codes: SU01, PFCG...)? I am not sure but probably he should have the next one:

 

 

 

Data Warehousing Workbench - Objects                         S_RS_ADMWB

Activity                                                   03                            ACTVT

Administrator Workbench object               SOURCESYS           RSADMWBOBJ

 

 

 

Please, investigate in this direction and let me know.

And so im clear when you are talking about BW user, you mean my standard developer login? or arew you thinking of a "internal SAP" system user?

 

Cheers

Gareth

Hello,

 

We connected our BWD to SQL and it worked fine.

We then connected our BWP to another SQL and the connection is fine as well, HOWEVER , we get GIBRISH see below .  Any ideas?

 

Thanks,

Hi Moshe,

 

That screenshot seems to be at BEx level. Have you loaded 'Customer' texts in BWP? For example, if you are using 0CUSTOMER infoobject as 'Customer' you have to load its texts:

 

 

Hope it helps!

Initially when i extracted the data i did and i have successfully loaded..Later in sql table a filed name was changed, but its not getting replicated after many tries in to BW

I read that in  sql we can not replicate change, is that true?? if not how can i replicate the changed table field to BW.

I am trying to extract data from MS SQL into SAP BW. the tables are in lower case. The lower case tables are not accessible for data load.
The SQL guys gave me a synonym table in upper case but this table I am not able to see in the list of tables available for extraction.
How can we access or extract data from MS SQL into SAP BW whose tables are in lower case.

At your info provider setting, turn on (allow lower case). and you can load your data.

Hello Carlos,

I've tried those steps with adding new roles to both users - the one that is viewing the context menu and the SQL user. Unfortunately, none of these works.

Do you know some other solutions?

Hi Karthik,

If you change a field in SQL table you have to refresh the default system proposal on BW side (Datasource: 'Proposal' tab). Then you have to add the new field -or to make sure the new name is correct ('Field' tab). And finally, please check that the datasource is bringing values for that field ('Preview' tab).

Thank you,

Carlos

Hi Carlos,

 

I am trying to setup the connection from a BW system running on AIX platform with Oracle as the database to MSSQL database. I am getting the below error thus wondering if this is supported from SAP point of view.

Error: No shared library found for the database with ID MSSQLS

 

I have gone though many links and some even suggesting to have the application server running on windows platform.

Hi,

in case you could not solve this problem:

https://launchpad.support.sap.com/#/notes/0001940873

 

This can be done in:

  1. Transaction RSCUSTV32:

  2. or from transaction SPRO: SAP Netweaver -> Business Warehouse -> General settings -> Hide 3.x Functions / Show obsolete Functions

Can someone give me some idea if I want to connect with MS SSAS cubes. Can I follow the same steps? or can I able to write MDX queries to pull the data from the cubes?

 

Thanks,
