About BPMN Events
 
About Throwing and Catching Events
A BPMN event represents something that happens during the execution of a process. An event affects the flow of the process and is usually triggered by some action in the process. In most cases, execution of the event results in some kind of action.
Before you work with BPMN events in Software AG Designer, you should be familiar with the BPMN 2.0 specification in general. For more information, see the BPMN specification at http://www.omg.org/spec/BPMN/2.0/.
In BPMN, the following primary event types are available:
*Start events
*Intermediate events
*End events
Each of these primary events can be expressed as various secondary event types. For example, a none start event, or a terminate end event. Software AG Designer does not support all of the event types that are defined in the BPMN 2.0 specification. The event types listed in the following table are supported.

Software AG Designer icon symbology conforms to BPMN 2.0 usage in form and line. However, the colors applied to some events may not be used by other modeling tools.
In general, the behavior of BPMN events in Software AG Designer conforms to the BPMN 2.0 specification.
For specific information about the implementation of these events in Software AG Designer, see the following topics:
*Start events: About Start Events.
*Intermediate events: About Intermediate Events.
*End events: About End Events.
