当执行流到达错误结束事件时，会结束该执行流并且抛出错误，该错误可以被错误边界事件捕获，如果没有定义任何的错误边界事件，那么其将会被当作无指定错误事件执行。因此，错误结束事件一般使用在子流程当中，如果错误事件结束，就会触发依附在该子流程上的错误边界事件。错误结束事件和错误边界事件需要一起使用才有意义，错误结束事件触发错误边界事件，错误边界时间捕获错误结束事件抛出的错误信息，而它们一般在嵌套子流程和调用子流程中使用。
错误结束事件图标：
实例流程图：
启动流程后自动进入子流程的Sub Task任务节点，然后进入单路选择，如果flag为true，直接完成，跳转到End Tast任务节点。如果flag为false，进入流程错误结束事件，抛出异常信息，错误边界事件捕获到错误信息，进入Error Task任务节点。
注意：此处的错误结束事件、错误边界事件引用同一个错误信息

}注意：
1、取消结束事件只能使用在事务子流程中
2、取消结束事件会触发依附在子流程上的取消边界事件（取消结束事件会被抛出，而取消边界事件则会捕获事件）
3、取消事件的触发还会导致补偿的触发
4、在BPMN2.0中对于已经完成的活动，可以使用补偿机制，而对于一些正在进行的活动，不能使用补偿机制，而使用取消机制
