Exceptions can occur anywhere in a process instance.

To display the details of a process instance.

An end event is the last step before the process instance is completed. The end event has a thicker circle border line than the start event.

Regardless which message arrives first, a process instance is created.

The icon specifies the actual type of event that will trigger the process instance creation.

Because this is the last component in the business process, the process instance ends after the output message is sent.

At runtime, the variables VP and VM have only one instance per process instance.

The My To Dos page will display after you start the business process instance.

You can generate CBE events during the process instance migration.

Process instance ID of the parent process, or null if no parent exists.

A terminate activity lets you stop a process instance as soon as possible without performing any compensation or fault handling.

Thus the effects of the activity on the process instance and the whole application system outside the process instance are gone.

Notice that parallel paths in the process instance can proceed and the process state remains running.

In such scenarios, it is the schema information that you need to process instance data rather than the validation.
