Unable to access Cost and budget information across tenant.

Hi Goodall, Kurt

There are a few common causes for the “Access denied” error when attempting to view cost data across tenants, which are outlined below:

Please verify that the users trying to access Cost Management data have the appropriate roles assigned. The Cost Management Reader or Contributor roles are typically required, and these should be granted at the correct scope whether it's a management group, subscription, or resource group. Additionally, only users with User Access Administrator or Owner roles have the ability to assign these roles to others.

When accessing cost data across different Azure Active Directory tenants, proper configuration of cross-tenant role-based access control (RBAC) is essential. If this setup is incorrect or incomplete, users may encounter access issues. Please ensure that RBAC settings are correctly configured for the external tenant’s subscription. After making changes, it may take up to one hour for access permissions to propagate.

Microsoft may occasionally update access control policies and mechanisms. While specific details on recent changes may not always be available, we recommend checking the official Microsoft documentation https://learn.microsoft.com/en-us/azure/cost-management-billing/ on Azure Cost Management regularly for the most current guidance and best practices.
