Travel agent last name identifying the Customers Employee, changing this Reservation.
If the employee identified by TravelAgentCode, TravelAgentFirstName and TravelAgentLastName is not known by sunnycars during creation of the Reservation, CarRentalAgentService will create a new TravelAgent for the operator(Agency). Instead of matching the TravelAgent simply by its code, TravelAgentCode, TravelAgentFirstName and TravelAgentLastName are used. Therefore, this property has to be set, if TravelAgentCode is and it's not desired to create a new TravelAgent.
