The preferred mechanism of configuring processes is to initially leave exceptions workflow off until the configuration has been completed.
In some circumstances this may not be possible, e.g. if you are using Duco Insight you are looking to test auto-close behaviours In these circumstances, additional exceptions will accumulate during the process setup that do not represent “real exceptions”.
These can be closed using the “Close all exceptions” button. This button is not available after change control has been switched on.
