The dual-write asynchronous integration feature in Project Operations enhances the customer invoicing process by enabling scalable and reliable data synchronization between Dataverse and Dynamics 365 Finance. This feature addresses the limitations of real-time dual-write sync, which is restricted to processing a maximum of 1,000 invoice lines per invoice.
With the introduction of asynchronous integration, this constraint is eliminated. The async model allows invoice data—including actuals, transaction connections, and invoice proposals—to be processed in the asynchronous mode. This enables the generation and synchronization of invoices with thousands of lines, ensuring that billing operations are not disrupted by system limitations.
