Example person was hired on 07/17/2019, attempting to assign the Line Manager who was hired a day after 07/18/2019 will not work within Manage Users.
Manager Users does not have the date effective update functionality.

The manager did not exist in the system until 07/18/2019 so would not exist when searching on 07/17/2019 and attempting to search for on that date.

In Manage User, Manager Search will be using the Hire Date of the worker to bring all persons active as of that day. If manager was hired after this date, then it won't be available.
