A «derive» Dependency must be from a UseCase or a Requirement towards a Requirement.

A «derive» Dependency relates a derived Requirement to its source Requirement. This typically involves analysis to determine the multiple derived Requirements supported by a source Requirement. Derived Requirements generally correspond to Requirements at the next level of the system hierarchy.

If you have a «derive» Dependency which is not from a UseCase or a Requirement toward a Requirement, you should delete it.
