Automatically resolve primary key merge conflict

Question

could you please suggest me the way I could automatically resolve primary key conflicts during a merge between Publisher and Subscriber. It seems Sql Server doesn't do it out of the box :(.

Conflict viewer shows me next message:

A row insert at '_publisher_server_' could not be propagated to '_subscriber_server_'. This failure can be caused by a constraint violation. Violation of PRIMARY KEY constraint 'PK_PartPlan_FD9D7F927172C0B5'. Cannot insert duplicate key in object '_table_name_'.

Thank you.
