A shared sales dashboard may need different visibility for each department. Review BigQuery row-level controls, the BI connection identity and exported files before commissioning a rollout.
When rolling out departmental BI, distinguish interface filters from access controls. A department selector does not prove that other departments’ data is inaccessible. Define who can retrieve which rows and fields through each route, then test with the identities actually used by consumers.
What BigQuery row-level controls do
The official documentation describes row access policies that show or hide table rows according to conditions. They can coexist with controls such as column-level security. Some operations, including certain table-replacement operations, can remove policies, so data-refresh procedures also need review.

The following is For f’s implementation guidance, not a guarantee that every BI product behaves identically. Validate the combination of connection method and permissions in the actual environment.
Start with a visibility matrix
Define record scope, such as an individual’s customers, a manager’s department or company-wide reporting for executives. Separately identify fields that should remain hidden even when a row is visible. Specify dual roles, temporary assignments and records without a department so developers do not have to invent exception rules.
Identify the principal used by the BI connection
Check whether queries run as the individual viewer or a shared service identity. With a shared identity, the viewer and the data-retrieving principal may differ. Record the identity recognized by actual queries and the returned data, rather than relying only on configuration descriptions.
Include data-access routes beyond the dashboard
Inventory CSV exports, scheduled delivery, shared links and connections from other analysis tools. Restrictions visible in a dashboard need separate verification in exported outputs. Agree with operations on file storage, recipients, cached results and previously distributed reports.
Illustrative example: publishing branch sales reports
For a shared report used by east and west branches, prepare test identities for each branch and for company-wide access. Check both that other branches’ records are hidden and that legitimate local sales remain visible. Include unassigned records and transfer-date boundaries, with business owners reviewing expected allowed and denied results.
Deliverables to agree before engagement
- An access matrix linking users, departments, rows, fields and connection identities
- Test results for dashboards, exports and scheduled delivery
- Procedures to recheck access after table refreshes and organizational changes
For estimates, specify connection methods, exceptional roles, delivery routes and administrative work as well as the number of screens. Test whether restrictions affect reporting speed or daily refreshes, and plan how to handle blocked legitimate work. Acceptance should cover usable reporting under the intended restrictions.
Is copying the dashboard for each department enough?
Separate dashboards do not by themselves restrict data access. Even with separate screens, test direct access and exports for cross-department exposure. Consider completing the access matrix and tests for one report before extending the approach to other departments.
Discuss the scope with For f
We can start by defining the scope around your current workflow and what you need to establish. You can discuss what you know even if documentation is incomplete.
