Enabling Exceptions workflow will switch-out the default Duco user interface with the Exceptions workflow interface used for break resolution. The new interface will appear for all runs made subsequent to enablement (prior runs will still show the default interface). This setting is typically configured once a process has been fully configured, with any required filters, rules, transformation, etc. already in place.
When creating a process, Exceptions workflow is listed as an option in the Settings menu.
However, you will most likely want to make this change from the Settings once your process has been fully configured.
To configure Exceptions workflow you will first need to select a Default group. Members of this group will have the ability to action on the exceptions for this process. Once this has been selected the Exceptions workflow enabled checkbox will be available to be checked. An optional checkbox is also available to enable Auto-close exceptions.
