Manager's ID is displayed instead of name in documents.
Employee Central Document Generation
A rule needs to be created as this is not possible via Direct Mapping. Selecting just supervisor or manager in the target field in direct mapping will give you the user id of the employee. Creating following business rule will help us to display the name in documents.
