We currently have a live connection from Tableau desktop version 10.1.5 to HANA database. I'm wondering what the various methods are for enacting security to control access to calculation views on the HANA database, that work with tableau. We mainly use HANA for reporting, so it copies over data from the source SAP system. Most of the reporting tables are set up as calculation views. We've had a really hard time figuring this out. Currently, once the live connection is established from Tableau to HANA, the user has access to everything on the database.
Do you utilize Tableau Server? User security/governance is a feature of Tableau Server and one of the many reasons to consider this solution - You can review the possibilities here: Permissions Reference
