Adding a Boundary Intermediate Event

To add a boundary intermediate event to an activity

1. Open the process model you want to work with in the process editor and do one of the following:

Right-click the activity you want to work with, click Add Boundary Event, and click the desired boundary event in the resulting menu. Only those boundary events that apply to the selected activity are available. For example, a boundary timer intermediate event is not available for a user task.

Drag a boundary event from the palette to an activity. If the boundary event is not supported by the activity, you will not be allowed to drop the event. Not all boundary events are available from the palette. See the note below.

In the process editor palette, click a boundary event type, then click the activity in the process editor where you want to place the new boundary event.

Note: The palette does not contain an entry for all possible boundary events. If you drag any of the following events onto an abstract, service, user, or rule task activity, or onto a call activity, it is added to the activity as noted in the following table.

If you drag this to the activity...	This event type is added to the activity:
Message start event	Non-interrupting boundary message intermediate event.
Signal start event	Non-interrupting boundary signal intermediate event.
Message end event	Non-interrupting boundary message intermediate event.
Signal end event	Non-interrupting boundary signal intermediate event.
Error end event	Interrupting boundary error intermediate event.

2. Add any transition lines and configure the boundary event as necessary in the Properties view.

3. Save the process.

Note: You can change the boundary event type after you add it. For more information, see Changing an Activity, Event, or Gateway Type.
