    Hi David,
    
    Are you being prompted for a s-user id? This is because KB articles are only accessible for clients with a valid SAP Maintenance contract.
    
    Please explain what you mean by “couldn’t open the link you have provided”.
    
    Thanks!

      Hi Julie ,
      
      I have read the KB article . My problem is not with HANA connection . Its with fetching data from Microsoft SQL server 2008 . Mean while i tried a sample job of the same above mentioned scenario from Microsoft SQL server 2008 to Flat file and i got this error shown below.
      
      So now i think that problem might be with the datastore . If so provide me the datastore configuration for Microsoft SQL server 2008.
      
      Please do the needful.
      
      Thanks in advance,

        Hello David,
        
        In your new example, the error indicates an issue with your repository database, not a datastore connection. A repository database is something completely different from a datastore connection.
        
        If you have concern about your connection to your MS SQL datastore, import a single table from the same datastore, make it a source, connect it to a Query transform, then view it by clicking on the magnifying glass. Do you see your data? If so, you don’t have a connection isssue to your MS SQL 2008 datastore.
        
        You can also review Extra Requirements for MS SQL Sever via the DS Installation Guide, page 24:
        
        http://help.sap.com/businessobject/product_guides/sbods42/en/ds_42_install_win_en.pdf
        
        Beyond this, please log into the SAP Support Portal and create a SAP Support Incident.
        
        Thank you,
        Julie

        Hi Julie,
        
        Thankyou for your reply.
        
        I’m able to view the data from the datastore . You have mentioned that it seems like an issue with repository database . Can you please elaborate on the same.
        
        Thanks,

        If you receive this message you may be using the wrong driver. For nearly all databases, you must use JDBC drivers with 64-bit machines.
        
        This information can be found in the documentation:

Hi David,

Looks like a 32 bit DSN is trying to contact a 64 bit application.

Can you please check if the ODBC DSN is created from the following 64 bit location

C:\Windows\SysWOW64\odbcad32.exe…

If it is created from the odbad32.exe application under System32 folder under Windows then it can cause an issue

Regards

Hi all ,

Sorry for updating this answer very late.

seems like its a bug in BODS 4.1 . My job server is Linux so cannot use the database type as SQL SERVER 2008 instead use ODBC .

Thanks,

David king.

  You can still use SQL Server 2008 R2 as database datastore as SQL Server Authentication is supported with Data Services on Linux Platform
