When deleting an analysis configuration or report from Enterprise Manager, the table that stores large information for the object is actually kept in the Enterprise Database. As such, it is possible to restore it. With the new system option of "Reduce database when deleting objects" enabled, the table used for internal storage of the selected object can be permanently removed, reclaiming the space in the database.
Note: once the table is deleted by enabling this option, it can not be retrieved in the database.

The option is available on version 13.3.0 onward. To enable this option:

1. Under Enterprise Manager, click "System Options | Miscellaneous"

2. Select "Reduce database space when deleting objects"
