Only a single case record may exist for a Case Key Value combination, for a given case workflow. Only upon a case being non existent or in Closed status, for that Case Key Value, for a cases workflow, may a new case be created.

The Case Journal shows the case records, containing the same data as the status bar in the case page, in grid form. The Case Journal will contain all cases for a Case Key Value combination, for a case workflow, ever created.
