About Boundary Intermediate Error Events
Boundary intermediate error events always interrupt, except for webMethods subprocesses (deprecated), where they are always non-interrupting. There is no option to configure the interrupting behavior of a boundary error intermediate event. This behavior is fixed and cannot be modified by the user.
If a boundary intermediate error event is not present, the step transitions using the process error handler step mechanism. For more information about the error handler step, see
Advanced Process Properties.
There are no advanced properties for a boundary error intermediate event.
