I'd like to confirm my understanding of the Valid Plan field on the Enrollment Parameters. It seems to me that the only way an employee would be enrolled in an invalid plan (ie. one that doesn't exist in their Benefit Group) would be if they were enrolled in it using Enrollment Overrides. The default Enrollment Parameters then do two things. If an employee is terminated, then the system will terminate all valid and invalid plans. for any other employee status, these invalid plans will be simply ignored. Is this correct?
