The reporting service provides data for retrospective analysis. Vantage makes use of the following data storage: * [Business Processing Reporting Warehouse](/vantage/developer/reporting/business-reporting) stores data about all transactions. * [Analytics Reporting Warehouse](/vantage/developer/reporting/analytics-reporting) stores data about changes in documents and fields processed by Process skills, which includes the Manual Review stage. You can download a data report from a Warehouse in CSV format using the Vantage API. Only users with **Tenant Administrator** or **Processing Supervisor** roles can download data reports. For more information, see [Role-based access control](/vantage/documentation/tenant-admin/tenant-management/role-based-access).
