Creating and Deleting Links

Using the references control you can enter links to items which are derived from the item you are editing (down traces), e.g. from requirements to specification:

To add references: click on the Create ... button, to select already existing item click on the Select button.

If you click on the break chain icon behind an existing reference, just the reference will be removed. The referred item will not be deleted itself.

To add or view up traces click on the Reference icon 

A dialog opens which allow you to view and modify the traceability tree of the selected item (see Reference Dialog).
