About Boundary Event Error Behavior in a Subprocess

Designer 10.7 | webMethods BPM Process Development Help | Process Engine Processing | Handling Process and Step Errors | About Boundary Event Error Behavior in a Subprocess

Boundary error events can be added to tasks within a subprocess, to the subprocess itself, or to both. In general, when a error occurs, it is caught by the boundary error event placed on the step or subprocess where the error occurred. If no boundary error event is present, the subprocess fails and is waiting to be resubmitted.

The following table describes the behavior of subprocess activity step errors in various situations:

An error occurs in a subprocess activity step	The activity step has a boundary error event	The subprocess has a boundary error event	Process has a process error step	Result:
	Yes	No	Not applicable	Error is caught by the activity step boundary error event.
	Yes	Yes	Not applicable	Error is caught by the activity step boundary error event.
	No	Yes	Not applicable	Error is caught by the subprocess boundary error event.
	No	No	Yes	The status of the subprocess is set to Failed and the subprocess is waiting for resubmission.
	No	No	No	The status of the subprocess is set to Failed and the subprocess is waiting for resubmission.

The following table describes the behavior of subprocess errors in various situations:

A subprocess executes an boundary error event	The subprocess has a boundary error event	Process has a process error step	Result:
	Yes	Not applicable	Error is caught by the subprocess boundary error event.
	No	Yes	The status of the subprocess is set to Failed and the subprocess is waiting for resubmission.
	No	No	The status of the subprocess is set to Failed and the subprocess is waiting for resubmission.
