Connect to your Microsoft Fabric tenant from Microsoft Purview in a different tenant (Preview)

  • 아티클

Important

Scanning a Microsoft Fabric tenant will bring in metadata and lineage from Fabric items including Power BI. The experience of registering a Fabric tenant and setting up a scan is similar to Power BI tenant and shared among all Fabric items. The scanning of Fabric items other than Power BI is currently in preview. The Supplemental Terms of Use for Microsoft Azure Previews include additional legal terms that apply to Azure features that are in beta, in preview, or otherwise not yet released into general availability.

This article outlines how to register a Microsoft Fabric tenant that's in a different tenant from your Microsoft Purview resource, and how to authenticate and interact with the Fabric source in Microsoft Purview. For more information about Microsoft Purview in general, read the introductory article.

Note

For scanning a Power BI tenant, see our Power BI documentation.

  • Empty workspaces are skipped.

Prerequisites

Before you start, make sure you have the following:

Authentication options

  • Service Principal
  • Delegated Authentication

Deployment checklist

The deployment checklist is a summary of all the steps you'll need to take to set up a cross-tenant Fabric source. You can use it during setup or for troubleshooting, to confirm you've followed all the necessary steps to connect.

Scan cross-tenant Fabric by using delegated authentication in a public network

  1. Make sure the Fabric tenant ID is entered correctly during the registration. By default, the Fabric tenant ID that exists in the same Microsoft Entra instance as Microsoft Purview will be populated.

  2. Make sure your Fabric metadata model is up to date by enabling metadata scanning.

  3. From the Azure portal, validate if the Microsoft Purview account network is set to public access.

  4. From the Fabric tenant admin portal, make sure the Fabric tenant is configured to allow a public network.

  5. Check your instance of Azure Key Vault to make sure:

    1. There are no typos in the password or secret.
    2. Microsoft Purview managed identity has get and list access to secrets.

  6. Review your credential to validate that the:

    1. Client ID matches the Application (Client) ID of the app registration.
    2. For delegated auth, username includes the user principal name, such as johndoe@contoso.com.

  7. In the Fabric Microsoft Entra tenant, validate the following Fabric admin user settings:

    1. The user is assigned to the Fabric administrator role.
    2. If the user is recently created, sign in with the user at least once, to make sure that the password is reset successfully, and the user can successfully initiate the session.
    3. There are no multifactor authentication or conditional access policies enforced on the user.

  8. In the Fabric Microsoft Entra tenant, validate the following app registration settings:

    1. The app registration exists in your Microsoft Entra tenant where the Fabric tenant is located.
    2. If service principal is used, under API permissions, the following delegated permissions are assigned with read for the following APIs:
      • Microsoft Graph openid
      • Microsoft Graph User.Read
    3. If delegated authentication is used, under API permissions, the following delegated permissions and grant admin consent for the tenant is set up with read for the following APIs:
      • Power BI Service Tenant.Read.All
      • Microsoft Graph openid
      • Microsoft Graph User.Read
    4. Under Authentication:
      1. Supported account types > Accounts in any organizational directory (Any Microsoft Entra directory - Multitenant) is selected.
      2. Implicit grant and hybrid flows > ID tokens (used for implicit and hybrid flows) is selected.
      3. Allow public client flows is enabled.

  9. In Fabric tenant, from Microsoft Entra tenant, make sure Service Principal is member of the new security group.

  10. On the Fabric Tenant Admin portal, validate if Allow service principals to use read-only admin APIs is enabled for the new security group.

Register the Fabric tenant

  1. From the options on the left, select Data Map.

  2. Select Register, and then select Fabric as your data source.

    Screenshot that shows the list of data sources available to choose.

  3. Give your Fabric instance a friendly name. The name must be 3 to 63 characters long, and must contain only letters, numbers, underscores, and hyphens. Spaces aren't allowed.

  4. Edit the Tenant ID field, to replace with the tenant for the cross-tenant Fabric that you want to register and scan. By default, Microsoft Purview's tenant ID is populated.

    Screenshot that shows the registration experience for cross-tenant Fabric.

Authentication to scan

To be able to scan your Microsoft Fabric tenant and review its metadata, you'll first need to create a way to authenticate with the Fabric tenant, and then give Microsoft Purview the authentication information.

Authenticate to Fabric tenant

In Microsoft Entra tenant, where Fabric tenant is located:

  1. In the Azure portal, search for Microsoft Entra ID.

  2. Create a new security group in your Microsoft Entra ID, by following Create a basic group and add members using Microsoft Entra ID.

    Tip

    You can skip this step if you already have a security group you want to use.

  3. Select Security as the Group Type.

    Screenshot of security group type.

  4. Select Members, then select + Add members.

  5. Search for your Microsoft Purview managed identity or service principal and select it.

    Screenshot showing how to add catalog by searching for its name.

    You should see a success notification showing you that it was added.

    Screenshot showing successful addition of catalog managed identity.

Associate the security group with Fabric tenant

  1. Log into the Fabric admin portal.

  2. Select the Tenant settings page.

    Important

    You need to be a Fabric Admin to see the tenant settings page.

  3. Select Admin API settings > Allow service principals to use read-only admin APIs.

  4. Select Specific security groups.

  5. Select Admin API settings > Enhance admin APIs responses with detailed metadata and Enhance admin APIs responses with DAX and mashup expressions > Enable the toggle to allow Microsoft Purview Data Map automatically discover the detailed metadata of Fabric datasets as part of its scans.

    Important

    After you update the Admin API settings on your Fabric tenant, wait around 15 minutes before registering a scan and test connection.

    Caution

    When you allow the security group you created to use read-only admin APIs, you also allow it to access the metadata (e.g. dashboard and report names, owners, descriptions, etc.) for all of your Fabric artifacts in this tenant. Once the metadata has been pulled into the Microsoft Purview, Microsoft Purview's permissions, not Fabric permissions, determine who can see that metadata.

    Note

    You can remove the security group from your developer settings, but the metadata previously extracted won't be removed from the Microsoft Purview account. You can delete it separately, if you wish.

Configure credentials for scans in Microsoft Purview

Service principal

  1. Create an app registration in your Microsoft Entra tenant where Fabric is located. Provide a web URL in the Redirect URI.

  5. Select Azure AutoResolveIntegrationRuntime from the dropdown list.

  6. For the Credential, select the credential you created for your service principal or delegated authentication.

    Screenshot that shows the Fabric scan setup, using Azure integration runtime for cross-tenant.

  7. Select Test connection before continuing to the next steps.

    If the test fails, select View Report to see the detailed status and troubleshoot the problem:

    1. Access - Failed status means that the user authentication failed. Validate if the username and password are correct. Review if the credential contains the correct client (app) ID from the app registration.
    2. Assets (+ lineage) - Failed status means that the authorization between Microsoft Purview and Fabric has failed. Make sure that the user is added to the Fabric administrator role.
    3. Detailed metadata (Enhanced) - Failed status means that the Fabric admin portal is disabled for the following setting: Enhance admin APIs responses with detailed metadata.

    Tip

    For more troubleshooting, see the deployment checklist to make sure you've covered every step in your scenario.
