Connect a Fabric workspace in Discovery to browse supported Lakehouse and Warehouse tables and import the ones you want to validate. Your customer execution Data Factory discovers the table metadata and checks access; source rows remain in your environment.

​
Before you connect

  • Complete environment setup and wait for the execution environment to become ready.
  • Use an Owner account in General Validation that is also an Admin or Member of the Fabric workspace.
  • Ask your Fabric administrator to allow the customer execution identity to use the required Fabric APIs. Tenant policy may also require an Entra administrator to approve the browser’s Fabric permission.
  • Confirm that Fabric capacity is active and that the execution factory can reach the supported SQL endpoints.
Review Supported data and tests for the supported table types, schemas, and validation limits.

​
Review workspace access

Guided setup requests Viewer access for the managed identity of your customer execution Data Factory. Viewer permits reads across the selected workspace, including Lakehouse and Warehouse SQL data. Review that scope with your Fabric administrator before connecting. Existing higher workspace permissions are preserved. Current setup and repair do not request a workspace role for the General Validation application. Your browser uses your Microsoft identity to complete setup; its Fabric token is not sent to the General Validation API.

​
Connect and import tables

  1. Open Discovery, choose Add source, and select Microsoft Fabric workspace.
  2. Choose Find my Fabric workspaces, sign in when prompted, and select the workspace. Review the execution identity and requested access.
  3. Choose Register and grant Viewer access. The first catalog refresh starts automatically after the connection completes.
  4. Browse the Lakehouse and Warehouse tables. Tables are listed automatically for items with a ready SQL endpoint.
  5. Select the tables you need and choose Import selected, or use Import & prepare for one item.
Import starts schema and table-access checks. Wait for each Dataset to become ready before creating a Pair. Workspace visibility or a Viewer grant alone does not establish that an imported table can run. Owners and Contributors can refresh the catalog and import datasets. Readers browse saved metadata without starting discovery activity.

​
Recover a catalog or preparation failure

A failed refresh retains the previous catalog. Tables from a failed item listing may remain visible, but cannot be newly imported until listing succeeds. Review the refreshed catalog before importing again. If an older import is no longer ready, follow its preparation or re-import instructions. Do not add unrelated storage or Azure SQL grants to resolve a Fabric-specific error. A paused Fabric capacity or blocked network connection needs its own correction.

​
Disconnect a workspace

An Organization Owner who is also a current Admin of the Fabric workspace opens the source’s Disconnect this Fabric source section and reviews the removal plan. If dependencies or other blockers are listed, follow the displayed guidance and contact support if no resolution is offered. Once removal is available, confirm the source name and choose Remove exact grants and source. The flow removes matching Viewer assignments created by General Validation. Preexisting or externally changed assignments are preserved. Earlier product-created application assignments can also appear in the removal plan. Removing a source does not delete its Fabric workspace or data. If your organization used an earlier connection flow, have your Fabric administrator review the General Validation application’s remaining direct and inherited workspace access. A connection update or registration removal alone does not establish that earlier access has been removed. For access or preparation errors, see Troubleshooting and Error codes.
