  • You have the correct permissions to classify tables and columns.
  • You have registeredregistered a data source, including these options:
    • Store Data ProfileData Profile.

    Note In order to improve Automatic Data Classification all Sample data and Profiling data is stored in the cloud.
  • Data Catalog experience is enabled in the DGC service configuration.
    This will give you access to the improved Schema asset page.
