Dynamics 365 Project Operations: Deprecate transaction origins
Project Operations is phasing out transaction origin records, replacing them with direct source document references on transaction records (journal lines, actuals, invoice line details). Any customizations, integrations, or reports that rely on transaction origin records will break and must be updated to use the new source document references.
Microsoft's description
Dynamics 365 Project Operations streamlines transaction processing by replacing separate transaction origin records with direct source document references on transaction records, including journal lines, actuals, and invoice line details. This approach reduces the database operations required to maintain links to originating time entries, expenses, and material usage logs, and enables the phased retirement of transaction origin record creation.
