Make Internal Requirement External

Elements in Enterprise Architect have internal requirements, or responsibilities (what they must do or accomplish). These can overlap or duplicate more formal requirements that the system in general must meet, so you might decide to make a single element's internal requirement into an external Requirement element (where the requirement can perhaps be implemented by multiple elements). You can make this conversion in one operation, using the Move External function.

Access On a diagram or in the Project Browser, right-click on element and select:

Properties > Requirements or

Properties Page | Requirements
