Dynamic Data Masking in OneLake Security

In scenarios where column-level security is applied, visuals in Power BI (e.g., Matrix) can fail for users without access to those columns.
To avoid breaking reports, some customers use Dynamic Data Masking (DDM) in SQL Endpoints instead of fully restricting column access.
OneLake Security currently doesn’t support this behavior.
We propose adding a DDM capability in OneLake Security, allowing masked values to be returned instead of errors, enabling seamless report rendering while still protecting sensitive data.
