Tableau uses the SAP OLE DB for OLAP provider (part of the Open Analysis Interfaces) to interact with SAP BW.
If you need more details, we have a knowledge base article that addresses the driver question in more detail as well as several other commonly asked questions: SAP BW FAQ | Tableau Software
Even after installing the driver I get the same error message as Bhramar.
It appears that there are additional steps needed to make the connection to HANA.
If you are still looking for answer -
Your SAP Security team needs to replicate Security profile for SAP HANA connection - When Tableau connects, it looks for SAP Driver (available from SAP Marketplace) and SAP HANA security parameters. This is strictly based on experience.
I am facing the same issue while connecting tableau to SAP HANA.
Can you please guide me the steps to resolve this issue.
Did you issue resolved?
if not, you can try downloading SAP_HANA_CLIENT_Version_102_5 from SAP Marketplace, as we are using the same for our project.
Once installed saphana.tdc file needs to be copied in D:\Users\xxxxxx\Documents\My Tableau Repository\Datasources.
And try to connect to your HANA server. Hope this should help.
