External Requirements

External requirements are those Requirement elements that have been connected to the current element using a Realize connector.

By creating a connector from an element to a 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 tab of the element Properties dialog, but they are marked external and cannot be directly edited (on selection, the tab 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.
