Part Number B10284-02
Oracle Workflow provides default error handling for both workflow processes and event subscription processing. The default handling is defined by error processes provided in a special item type called System: Error, and, for events, by a special subscription to the Unexpected event with a source type of Error. You can also choose to define your own custom error handling by creating custom error processes and subscriptions.
