Once you install the Hyperion System 9 Planningtm Planning Details ADM driver, you may choose Planning Details as a database connection. The Planning Details ADM driver is optimized as a data source to provide features such as supporting details, planning unit annotations and metadata filtering. If your report grid does not use those Planning features, for optimal performance, choose Oracle Essbase as the database connection for your report. For more information, see Showing Supporting Detail for Planning and PlanningAnnotations.
