Author a Restricted Data Policy

Build a data policy that only applies to data sources you own

Data owners who are not governors can write restricted subscription and data policies, which allow them to enforce policies on multiple data sources simultaneously, eliminating the need to write redundant local policies.

Unlike global policies, the application of these policies is restricted to the data sources owned by the users or groups specified in the policy and will change as users' ownerships change.
