How to resolve human ownership when a service principal is listed as owner in Microsoft Purview?

Hi @Raza, Noor Ahmad
Adding to the above, in practice most teams don’t rely on the “owner” field coming from the source when it shows a service principal, since that represents only the execution identity.

A common approach is to define actual ownership at the collection/domain level using Purview roles (Data Owner/Curator) and maintain a separate mapping of service principals to owning teams outside Purview (for example in Entra ID or internal documentation).

If you need ownership visibility at the asset level, you can also use custom metadata fields (like Business Owner/Data Steward) and populate them manually or via automation.

This way, governance ownership remains accurate while still allowing service principals for scanning and pipelines.

Microsoft Purview doesn’t provide an automatic, built‑in mechanism to translate a service principal that appears as an asset owner into a human governance owner. The platform separates:

• Technical identities (service principals, managed identities) used for scanning and automation
• Governance roles (Data Owner, Data Curator, Data Source Admin, Collection Admin, Domain Admin) that are assigned to people or groups

Within Purview, governance ownership is modeled and enforced through domains, collections, and Purview roles, not through the technical “owner” metadata discovered from source systems.

A practical pattern is:

1. Use Purview roles and collections to represent governance ownership
   • Design a domains/collections hierarchy that aligns with business domains, regions, or data stages, and assign:
     • Domain admins / Collection admins for administrative control
     • Data Curators / Data Readers / Data Source Admins at appropriate collection levels for operational and stewardship responsibilities
   • This way, governance ownership is expressed by who has Purview roles on the collection where the asset lives, rather than by the technical owner field on the asset.
   • Best practices recommend:
     • Minimizing the number of Purview Administrators, domain admins, and collection admins
     • Assigning roles to groups instead of individuals
     • Assigning a service principal at the root collection for automation purposes, while humans hold the governance roles.
2. Treat service principals as execution identities, not governance owners
   • Service principals and managed identities are recommended for scanning and automation (for example, as Purview credentials or automation identities), but they are just non‑human security principals.
   • They can be assigned Purview roles (for automation), but accountability should be modeled via:
     • The team or group that owns the collection/domain
     • Organizational processes that define who is responsible for each domain/collection
3. Model human ownership at the collection/domain level instead of per‑asset technical owner
   • For data democratization, one recommended pattern is:
     • Use a single domain and assign Data Reader at the default domain to broad user groups
     • Assign Data Source Admin and Data Curator roles at subcollection levels to the corresponding data management and governance teams
   • For restricted environments, assign Data Reader / Data Curator only at specific collections (for example, US vs LATAM collections) so that ownership and responsibility are clearly scoped.
   • In both cases, the governance owner is the team with roles on the collection, not the service principal that appears in technical metadata.
4. External resolution of service principal → human is outside Purview’s core model
   • Purview supports assigning roles to service principals, managed identities, users, guest users, and security groups from Microsoft Entra ID.
   • Any mapping from a service principal to its “owning” team (for example, via Microsoft Entra or Microsoft Graph) is an external process and not part of Purview’s governance semantics.
   • In practice, organizations:
     • Use Entra ID and internal processes to define who owns each service principal
     • Use Purview domains/collections and roles to define who owns each data domain and collection
   • The reliable, supported governance pattern is to rely on Purview roles and collection/domain structure for ownership, not on the technical owner metadata populated from source systems.

In summary, the recommended approach is to:

• Use service principals strictly as execution identities for scanning and automation
• Express human/governance ownership via Purview domains, collections, and role assignments to users/groups
• Keep any service principal → human mapping as an external directory/governance process, not as the primary ownership mechanism in Purview.
