A message in a Sequence diagram represents a dynamic interaction from one element to another. Sometimes when you are designing your model you might have to change either the start or end point of a message as the responsibilities of elements change during design. For this reason, Enterprise Architect enables you to change the message scope by setting a new start or end element.
Change Message Scope
To change message scope, follow the steps below:
|1.||Select the message in the Sequence diagram.|
|2.||Right-click on the message to open the context menu.|
|3.||Select Set Message Scope.|
|4.||In the pop up dialog, click on the drop-down arrows in the From Element and To Element fields, and select the required elements.|
|5.||Click on the OK button to save changes.|
The message is re-routed to meet your changed requirements.
