Auditors want column-level lineage and we cannot produce it
A financial-services CDO is preparing for a regulatory review. The auditor has asked for column-level lineage of all regulatory reporting figures from source through transformation to consumption. The current catalogue is partial, lineage is informal, and the data team is spending weeks reconstructing flows.
Trigger — Regulator request; lineage cannot be produced on demand.
Good outcome — Purview Data Governance live across Fabric, Databricks, and Snowflake; column-level lineage end-to-end; data products with named owners.
