Duplicate Address Book entries may cause issues with data accuracy, reporting, and auditing. This new enhancement for 9.2 provides functionality to validate the data being entered to prevent duplicate address book records from being created. You can specify whether you want the system to issue a warning or error message when it finds records with the same alpha name, city, and zip code combination or the same tax ID.
