* [**Call Activity**](/reference/bpmn20/subprocesses/call-activity) — Call a process from another process.
* [**Event Subprocess**](/reference/bpmn20/subprocesses/event-subprocess) — Event-driven subprocess.
* [**Transaction Subprocess**](/reference/bpmn20/subprocesses/transaction-subprocess) — Model business transactions.
