I am configuring one benefits plan and want to attach multiple life events like promotion, add a child, hire, etc that should re-calculate the standard rate amount and rate start date of the employee enrollment. These life events should be added on eligibility page or enrolment page? And what is the difference in LEs attached at these two places?
