Employee Must Be Unique
Everyone is an individual after all...
Employee entities in Youmanage must be unique, if you are receiving this error response then you have tried to create or update an employee so that it matches another in the system.
Uniqueness for the Employee entity is determined by the combination of FirstName, LastName, KnownAs and WorkEmail. If these fields are the same for two Employee entities then you will receive this error response.
Ensure that when updating Employee entities you do not give them the same identifying features as others in the system. If you want to restart an Employee in the system then you should update their details rather than create a new record for them.
