- You see the error "New Record is trying to replace an In Use Local System Id Invalid Request" in your Local Bibliographic Data Sync exception report.
- Data Sync
That error occurs if two different records (that match to different OCNs) are sent with the same Local system number and holdings are requested for both records, then Local Bib Data will only be created on one record. The second record will not have LBD created due to the duplicate LSN, ie LSN already in use on another OCN.
There is more on Data Synchronization reports.
