The Workflow Engine records information regarding errors that occur during the lifetime of a workflow process instance. A workflow administrator can use this information for troubleshooting problems with the process instance. This includes re-trying or aborting failed workflow process instances. Re-trying a failed process instance instructs the Workflow Engine to re-enact the workflow process instance from where it failed. Alternatively, a workflow administrator can abort a process instance. This stops the process instance and it's activities and closes any tasks associated with manual activities in the process instance. Depending on where the process was aborted, some manual steps may be required to complete before the process is actually aborted.
