Important: If you intend to use Job Appointments and you also use TimeZone views in Service Management, your users must use the Signature Alternate Dynamics versions of the Customer Maintenance, Customer Address Maintenance, and Customer Class setup windows. These windows contain information that is specifically used by Signature during the appointment scheduling process. to set up GP Customers and Addresses/Locations.  Failure to use the Alternate Customer Maintenance window will result in job appointments not being properly displayed in Schedule.
