Detecting and merging duplicate contacts
Because creating contacts can result in duplicate contact records, there are features in ContactManager to detect duplicate contacts and enable merging them. A user with appropriate privileges in ContactManager can run Duplicate Contacts Finder batch processing to detect duplicate contacts, and then merge each duplicate contact in the Merge Contacts screen.
Important: The first time you run Duplicate Contacts Finder batch processing, it can perform a large number of comparisons requiring considerable application resources. You can limit the number of contacts it processes by setting a processing time and date before which contacts are ignored. For more information, see Configuring Duplicate Contacts Finder batch processing. Additionally, Guidewire recommends that you set the work queue to run initially at a time when general access to your server is restricted. You might also need to allocate time for a ContactManager user to resolve what is likely to be a large number of duplicate contacts.
