Category: User functions
USER functions in Tableau are specialized functions used to identify and manage user-related information within a Tableau environment. These functions enable personalized, secure, and dynamic content delivery by leveraging information about the current logged-in user, their group, or their domain credentials.
Purpose
The main purpose of USER functions in Tableau is to:
Customize dashboards and visualizations based on who is viewing them.
Enforce row-level security by restricting data visibility depending on the logged-in user.
Enable user-specific filtering to ensure each user sees only the data relevant to their role or region.
Enhance collaboration and security in multi-user environments such as Tableau Server or Tableau Cloud.
These functions are essential for creating personalized experiences and maintaining data confidentiality in enterprise analytics.
Practical Use Cases
Row-Level Security (RLS): Limit data visibility based on the logged-in user’s credentials or group.
Personalized Dashboards: Show different KPIs, names, or regions depending on who is logged in.
Group-Based Access Control: Restrict sensitive metrics (e.g., financials) to specific roles like “Finance” or “Executives.”
Audit & Tracking: Monitor who accessed specific dashboards or data segments.
Multi-Tenant Dashboards: Display tenant-specific data for different clients or business units using a single dashboard.
| Function | Description |
|---|---|
| FULLNAME() | Returns the full name of the current user. |
| ISFULLNAME | Returns TRUE if the current user’s full name matches the specified name; otherwise, returns FALSE. |
| ISMEMBEROF | Returns TRUE if the current Tableau user belongs to a group matching the specified name, FALSE if not, and NULL if the user is not signed in. |
| ISUSERNAME | Returns TRUE if the current user’s username matches the specified username; otherwise, returns FALSE. |
| USERDOMAIN() | Returns the domain associated with the current user account. |
| USERNAME() | Returns the username of the current user. |
| USERATTRIBUTE | If the specified <attribute_name> exists in the JSON Web Token (JWT) passed to Tableau, this function returns its first value. Returns NULL if the attribute is not present. |
| USERATTRIBUTEINCLUDES | Returns TRUE if the given <attribute_name> exists in the JWT and at least one of its values matches the specified <expected_value>. Returns FALSE otherwise. |

USER functions are used to identify and manage user-specific information to create secure, personalized, and dynamic dashboards.
The USERNAME() function returns the username of the person currently logged into Tableau Server or Tableau Cloud.
Use USERNAME() or ISMEMBEROF() functions in calculated fields to create row-level security filters.
USERNAME() returns the login ID, while FULLNAME() returns the user’s full display name as configured in Tableau Server or Tableau Cloud.
Yes, but in Tableau Desktop they return the local system username. On Tableau Server or Cloud, they return the authenticated Tableau user credentials.
