It enables secure, tailored access and control, ensuring that users view data relevant to their domain. ## Support level: Basic - Business logic: Ensure that data goes into the proper domain for the application’s service provider use cases. - The application supports domain separation at run time. The domain separation includes separation from the user interface, cache keys, reporting, roll-ups, and aggregations. - The owner of the instance must set up the application to function across multiple tenants.
