Boundary Escalation Event Activity

The Boundary Escalation Event activity redirects a process to an alternative flow by throwing an escalation. This activity attaches exclusively to an embedded sub-process or a call activity. When triggered by an escalation event from a call activity, it passes the call activity's defined output variables to its own scope.

Action Types & Examples

Throw Escalation

• Format: string
• Example Result: "myProcessEscalation"

Implementation Examples

Field Setup - Escalation reference: myProcessEscalation

Execution Parameters - escalationRef: myProcessEscalation

Technical Notes

The Boundary Escalation Event activity is designed to catch and react to escalations. It can only be attached to an embedded sub-process or a call activity because escalations are typically initiated by an escalation intermediate throw event or an escalation end event. A key behavior is that upon being triggered by an escalation from a call activity, any defined output variables from that call activity are automatically propagated to the scope of the boundary event.
