Function documentationDuplicate Check for Accounts and Contacts


You can implement a check that identifies potentially duplicate accounts or contacts during creation or editing and notifies the user. The user can decide whether the new account or contact is required or is in fact a duplicate of an existing account or contact. Duplicate accounts can be discarded or merged with another account. For more information about merging duplicates, see Data Cleansing.


The duplicate check uses the interface of the Business Address Services. You activate the duplicate check in Customizing for SAP NetWeaver, under Start of the navigation path Application Server Next navigation step Basis Services Next navigation step Address Management Next navigation step Duplicate Check Next navigation step Activate Duplicate Check and Determine Limit for BAPIs End of the navigation path.

Make sure that the duplicate check has been activated for both index pools (tables BUT000 and BUT052).


The duplicate check can be implemented for accounts only, contacts only, or for both.

The duplicate check is executed in the SAP CRM system in create and edit mode.

The duplicate check uses the interface of the SAP NetWeaver Business Address Services. For more information, see Duplicate Check.
