Employees are enrolled to benefit plans either of two ways:
Via the self-service functionality where requests are entered and processed by the plan administrator. After authorizing a request the information is automatically updating the employee benefit plan enrollment in the Employee window..
Via the direct updating of the employee files. In this case there is no web enabled self-service functionality present, and the plan administrator enters the information manually from the forms filled in by the employees.
The enrollment information includes both historical information as well as the current enrollment.
