You can only add additional control flow inputs and outputs to an activity after dragging and dropping it into a reusing process model.
当您将某个活动拖放到采用重用方法的流程模型中之后，只能向该活动添加更多的控制流输入和输出。
Fully handling the exceptions in an automated way would add a lot of complexity to the process flow, and to the technology solution needed to support it.
以自动的方式完全处理异常会使过程流和支持它的技术解决方案变得非常复杂。
First, you need to add an assign activity to your process control flow before the invoke activity (see Figure 10).
首先，在调用活动之前，您需要将分派活动添加到流程控制流(请参见图10)。
As shown in the Figure 10 showing the business process editor with the macro flow that contain Receive and Reply activity, we add the human task by dragging it from palette.
图10展示了具有宏流(macro flow)的业务流程，该宏流包含了Receive和Reply活动，我们可以从面板中拖拽humanTask来添加它。
Addition actions: These actions add a node to an existing one in the process tree; for example, you can add a scope activity to a process, or a while activity to a flow.
添加操作：这些操作向流程树中已经存在的一个节点添加一个节点；例如，您可以向一个process添加一个scope活动，或者向一个flow添加一个while活动。
