    Error: “Cannot insert multiple records in Source document accounting event reference identity (SourceDocumentAcctEventReferenceIdentity). Accounting event: 0, 0. A time-out occurred in the database while the query was executing.”

    When i Go to Modules –> General ledger –> Inquiries and reports –> Accounting Source Explorer Click on the Drop-down of Financial Dimension Set and Select ‘All’ or any set from the list
    In D365F&O

    This usually points to a data volume / query timeout issue in Accounting Source Explorer, especially when selecting ā€œAllā€ financial dimension sets.

    A few things to check:

    Try filtering instead of selecting All. The query becomes very heavy with large datasets

    Check if there’s data inconsistency or duplicate references in SourceDocumentAcctEventReferenceIdentity

    Review batch jobs / cleanup jobs. Sometimes old accounting event data causes issues

    Make sure your environment isn’t hitting SQL timeout limits (common in large production DBs)

    If it started recently, check for customizations or recent data imports

    If it persists, running a database consistency check and reviewing telemetry in LCS can help identify the exact query causing the timeout

    In most cases, it’s not a functional issue. It’s performance + data volume combined with that ā€œAllā€ selection
