Assignable scopes (1)
/
Practical scope
Assign at the Azure management group, subscription, or resource group whose costs the principal must inspect. Parent assignments inherit to child scopes; billing-account and billing-profile access use provider-specific billing roles rather than this Azure hierarchy alone.
Common use cases (2)
- Analyze costs, forecasts, budgets, exports, and allocation for an Azure scope without changing settings.
- Provide finance, FinOps, audit, or workload owners with cost visibility for their responsibility boundary.
Prerequisites (2)
- Identify the Azure or billing scope that contains the required cost data.
- Confirm the principal needs configuration visibility but not budget or export changes.
Best practices (2)
- Assign at the narrowest reporting scope and use management-group scope only for organization-wide FinOps teams.
- Keep financial exports and detailed usage data in approved destinations with separate access control.
Security considerations (2)
- Cost data reveals resource usage, spend, service mix, and organizational structure.
- The role has no Cost Management writes or DataActions and cannot modify billed resources.
Assignment guidance
Assign to analysts and stakeholders at the cost scope they are authorized to view. Escalate to Cost Management Contributor only for approved budget, export, or configuration changes.
