In the Metadb reporting database, the folio_source_record.marc__t table should have a unique srs_id associated with each instance ID. However, in early November 2025, the Reporting Team noticed that, for some records (which now varies daily from zero to thousands), there were multiple srs_ids associated with each instance_HRID. The multiples were older versions of the marc record, which normally would not appear in the marc__t that table. The marc__t table should include only records where the state of the record is 'ACTUAL,' but it is including records where the state field is 'OLD.' So we are getting duplicate counts of the same record in cases where the record has been updated. This issue came up before with LDP software and was addressed. There is code to address this issue for the Metadb software, but it is not clear that it the code is working correctly in Metadb. The Reporting Team is working with Index Data to address this problem.
