External Requirements

External requirements are those Requirement elements that have been connected to the current element using a Realization connector. By creating the connector from the element to the requirement, you create an expectation that the element must implement the requirement as part of the system solution.

In Enterprise Architect, linked requirements are shown in the Requirements page of the element Properties dialog, but they are marked external and cannot be directly edited (on selection, the page fields are grayed out).

Double-click an external requirement in the list to activate the Properties dialog for the associated requirement, where you can view and modify the requirement details and check the requirement hierarchy details.
