Scanning Fabric Lakehouse and Warehouse Tables in Purview

Dong Li 0

How can the Purview data map be configured to scan Fabric Lakehouse and Warehouse tables at a more granular level, beyond just the item level metadata?

@Anonymous Thanks for your quick response. I tried several times but can't scan the sub-items, may I ask is this Lakehouse tables/files scan preview already in all regions or just in specific region.

Hi Dong Li,

Thanks for reaching out on Microsoft Q&A !

Yes granular level scan is available in Purview data map User's image

Register Fabric as a source in Purview

In Purview Studio > Data Map > Sources > Register > Microsoft Fabric (same tenant).
Authenticate with the service principal (client ID/secret or Key Vault).
Create & run the scan
In Purview Studio > Data Map > your Fabric source > New scan.

Choose scope (all workspaces or selected workspaces).

Set a schedule if desired.
Run the scan and watch Monitor

Verify sub-item (table/column) results

After a successful scan, open Unified Catalog and browse your Lakehouse. You should now see tables with columns & data types (sub-item metadata) for Lakehouse tables/files.

Remember: sub-item metadata is preview and limited to Lakehous,sub-item lineage isn’t yet supported.

Please refer the Microsoft official documents for the steps
