Content (please ensure you mask any confidential information): Termination of coverage for Unrestricted enrollments with either termination or global transfer is an issue with Unretsricted benefit relation and the solution documented is to use the Active ben relationhip lookup code to be enabled so that system allows event processing even after termination of employee.
