  • Hi BanuMurali​ ,

    Thanks for the clarification. Sensitivity labels in Microsoft Purview Data Map are currently in preview. While auto-labeling is supported for some data sources, Fabric as a data source is not supported for auto-labeling at this time.

    Refer to: https://learn.microsoft.com/en-us/purview/data-map-data-sources#services-and-apps 

    Learn about sensitivity labels in Microsoft Purview Data Map (preview) | Microsoft Learn

    Key points to note:

    • Custom Sensitive Information Types (SITs) are not supported in Purview Data Map currently.
    • For supported sources, only auto-labeling is available; manual labeling is not supported at this time.

    A lot more is covered in this good list of FAQs here: Sensitivity labels in Microsoft Purview Data Map FAQ (preview) | Microsoft Learn

    Hope this helps!

      Hi Prathista Ilango​ ,

      Thanks for the clarification!!

      It would really help us.

      If MS Fabric is not supported in Auto labelling policy as a source, Can you please confirm why it was listed in the MS Purview Information Protection - sensitivity label scope - 'Files and other Data Assets'.

      Can you please help as me how I efficiently use the auto labelling policy in MS Purview for Fabric as a source.

      1. Any roadmap for Fabric as a source to support auto labelling policy in Purview data map and to support custom Sensitive info types?

      2. In general, Any roadmap for Custom Sensitive Information Types (SITs) to support in Purview Data Map for currently supported sources (Azure SQL, Azure Synapse, Azure Cosmos DB, AWS RDS)

      Can you please help me on this, we are planning to implement Auto labelling for fabric assets in Purview Data catalog through Data Map, If we get clarification on above question it would really help us to plan it.

      Thanks again!!

      Regards,

      Banu

      Hi Prathista Ilango​,

      Thanks for clarification !!

       

      Can you please let me know, currently is there any road map/ immediate release for Fabric as a source to support auto labelling polices in MS Purview. 

      We are planning to implement auto labelling for Fabric assets in Purview Unified catalog using data map scan. It would be more helpful for us to plan accordingly.

      Regards,

      Banu

    Hi Prathista Ilango​ ,

     

    Thanks for the details!!

    I was expecting auto labelling sensitivity labels for Fabric data assets in Purview Unified Catalog.

    For example: I have created sensitivity label 'Test_Internal' (Scope: File and other data assets) and I have created an auto labelling policy for 'Test_Internal' and within the I have added SIT as 'Phone Number (keywords)'

    Assume I have an employee table (its have employee phone number) in Fabric Lakehouse When I do the Purview data map scan it captures metadata details of the employee table (column level details) after the data map scan succeeded fabric data assets schema level information available in Unified catalog for discovery.

     My question was while capturing metadata, does Purview Auto labelling the Phone Number column as 'Test_Internal' at schema level in Purview Unified Catalog (not in Fabric).

    Kindly let me know if you require any further details.

    Its quite urgent, Can you please confirm it asap.

     

    Thanks,

    Banu

     

  • Hello BanuMurali,

    Automatically apply sensitivity labels is only possible via Inheritance from data sources or downstream inheritance. Refer to: https://learn.microsoft.com/en-us/fabric/governance/protected-sensitivity-labels#how-protected-labels-work-in-fabric-and-power-bi 

    https://learn.microsoft.com/en-us/fabric/governance/protected-sensitivity-labels#relaxations-to-accommodate-automatic-labeling-scenarios 

    For example, if auto labeling is applied for Azure Synapse Analytics or Azure SQL Database as data sources, the data remains classified when brought into Power BI. Or, say if the Power BI report has the label applied manually, dashboard inherits this applied label automatically.

    Hope that clarifies. 

    Refer to: Sensitivity label inheritance from data sources in Power BI - Microsoft Fabric | Microsoft Learn

    Sensitivity label downstream inheritance in Power BI - Microsoft Fabric | Microsoft Learn

    Also refer to: Set or remove sensitivity labels programmatically with admin APIs - Microsoft Fabric | Microsoft Learn if you are looking to programmatically set/remove labels for large volumes of data. 

    Hope this helps!
