As an administrator, you should check contact data saved in the CRM regularly for duplicates and delete or consolidate them.
All master records with duplicates are indicated in a list. You can join the duplicates with the master record in the list. For this, the Duplicate management menu item is available in the Administration/Tools menu. The test mechanism used for the check is identical with the duplicate check performed when a contact is created, and works with the preset search depth 2 (no matter whether a different search depth is set via the PSA_QUE_DEP_ * environment variables).
