Important

This feature 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.

When a user updates an asset in Microsoft Purview, data map history logs that change and makes the information available in the Microsoft Purview portal. Information about who added or edited an asset, what edits were made, and when the edit happened, is stored for reference later. This information helps data auditors and business owners to maintain compliance and security in their Microsoft Purview accounts. It also allows data stewards and admins to debug issues and curation in their data assets.

Data map history is available to users in both the free and enterprise versions of Microsoft Purview.

Currently, you can view your assets' history either:
