Creating Traceability Links Between Objects from Different Models
You can create traceability links between any objects (including objects in different models) from the dependent object's property sheet. The model that contains the influent object must be open in the workspace.
Open the property sheet of the object, and click the Traceability Links tab.
Click the Add Objects tool to open the Add Objects dialog box.
Select a model from among the models open in the workspace from the Model box, (optionally) a package from the list, and an object from one of the sub- tabs and then click OK to add a traceability link to it.
The traceability link you have created is listed in the List of Traceability Links (available from Model > Traceability Links) and, if the objects are in the same diagram, as an oriented link symbol.
[optional] Enter a type to further identify the traceability link you have just created in the Link Type column. You can specify link types for selection (see Creating New Types of Traceability Links).
Click OK to close the property sheet and return to the diagram.
