You can create additional items in a BPMN model. These
items further define the model and can be used in a service model
to further refine the BPMN model.
To create a service interface, signal, or item definition:
- In the Project Explorer, right-click the corresponding
folder in the BPMN package.
- Click Add .
Attention: The element does not appear in the BPMN diagram except
a message that is created in a Collaborative BPMN model..
- In the Properties view, on the General
page, you can further specify properties to the element.
