Boundary events are used to handle exception events that occur throughout a process on a specific activity. When an interrupting boundary event is triggered, the activity is stopped and the flow of the boundary event is taken. When a non-interrupting boundary event is triggered, the flow of the boundary event runs in parallel with the normal process flow.
Web Modelers can assign the Boundary Events to Sub-Processes and Tasks when mapping processes on Graph Edit Mode.
This table explains the different characteristics and types of the Boundary Events:
| Boundary Events | Symbol |
|---|---|
| Event Characteristic | Interrupting:  Non-Interrupting:  |
| Event Type | None Message:  Timer:  Escalation:  Conditional:  Link:  Error:  Cancel:  Compensation:  Signal:  Multiple:  Parallel Multiple:  |
