Row-level security (RLS) in Tableau restricts the rows of data a certain user can see in a workbook. This differs from Tableau permissions, which control access to content and feature functionality.
How do you provide row level security in Tableau?
Tableau offers the following approaches to row-level security:
- Create a user filter and map users to values manually. This method is convenient but high maintenance, and security can be tentative.
- Create a dynamic filter using a security field in the data.
