After installing the Planning Details ADM driver, you can choose Planning Details as a database connection for Oracle Hyperion Financial Reporting Studio. The Planning Details ADM driver is optimized as a data source to provide Oracle Hyperion Planning features such as supporting details, planning unit annotations, and metadata filtering. If your report grid does not use Planningfeatures, for optimal performance, choose Essbase as the database connection. See the Oracle Hyperion Financial Reporting Studio User's Guide.
