If you are using the other SysML requirement relationships, you should not use the more generic trace link.
To create a trace relationship on a diagram
1. On the diagram's toolbar, click the Trace Dependency button.
2. Click the item that is traced, and then click the item that is traced from.

You can create trace relationships through an appropriate pane. For more information, see Creating a trace relationship through a pane.
