Column-level lineage view in Microsoft Fabric (Lakehouse / SQL / Pipelines)

[grantk]

Microsoft Fabric currently provides lineage at the item level (datasets, lakehouses, notebooks, pipelines), but does not expose column-level lineage within Fabric itself.

For teams building transformations using:

• Fabric Lakehouse (Delta tables)
• SQL Analytics Endpoints
• Dataflows Gen2
• Pipelines / Notebooks

there is no way to see how individual columns flow, transform, or propagate between sources and downstream tables/views inside Fabric.

Ask:

Provide a column-level lineage view directly in Microsoft Fabric, showing:

• Source column -> target column mappings
• Transformation paths across notebooks, pipelines, SQL, and dataflows
• Cross-artifact lineage (Lakehouse -> SQL Endpoint -> Dataset, etc.)

Limits:

• Fabric lineage graph only shows artifact-level relationships
• No visibility into column-level dependencies
• Purview does not currently provide complete or end-to-end column-level lineage for Fabric workloads.
