BULK: Subfield override not finding match when matching fields in records

Problem Symptoms

•  Matching 035 subfield 9 to incoming 019 subfield a in duplicate detection
•  When value of 035 subfield 9 matches 019 subfield a, but multiple 019 subfields a, no match found and record added instead of merged/replaced

Cause

Multiple 019 subfields a are normalized into a single string, so will not match one subfield instance to the existing value.

Resolution

Discard & analyze any records meeting this criteria:

1. In System Administration > Cataloging > Bibliographic Duplicate Detection > {duplicate detection profile} > Edit > Profile, check the box for "Discard incoming records that do not match existing records" which will write any records that do not find matches to a separate file on the server rather than adding them.
2. After import review the file of records & decide how to proceed. Options may include:
   1. Separate 019 subfields a into separate 019 fields
   2. Manually merge records in the Cataloging client.
   3. If using Replace, import records and then use Overlay Bibliographic function in Cataloging client to overlay duplicates.
