    Question

    How does Bi-Directional Merge work?

    Answer

    Bi-Directional Merge determines whether to keep the incoming or existing record when a match is found, and merges fiels from the lower quality record into the higher quality record. 

    • If the incoming record is higher quality than existing record (according to Quality Hierarchy): merge fields from the existing record are added to the incoming record, and the incoming record replaces the existing record. This is the same as Merge duplicate handling.
    • If the incoming record is lower quality than existing record (according to Quality Hierarchy): merge fields from the incoming record are added to the existing record, and the incoming record is discarded.

    Additional Information

    The system checks for quality based on the Quality Hierarchy as set in the Bibliographic Duplicate Detection Profile. For more information on the Quality Hierarchy and Bi-Directional Merge, see "How does Quality Hierarchy work with Bi-Directional Merge?"
