For real-time integration between Salesforce and the ERP system, Platform Events are well-suited as they enable Salesforce to publish an event immediately when an opportunity is marked as Closed Won. The ERP can then subscribe to these events and retrieve the necessary account and opportunity data.

Using Platform Events for Real-Time Updates: Platform Events facilitate an event-driven architecture where Salesforce can notify external systems instantly when specific changes occur, such as a Closed Won opportunity. This ensures that updates are transmitted to the ERP promptly.

Efficient Data Synchronization: With this approach, the ERP system can listen for these events and retrieve only the relevant records, reducing the need for frequent polling or scheduled jobs.

Option A (scripting ERP to fetch data) relies on periodic polling, which may not meet real-time requirements, and Option C (report subscription) does not provide immediate updates. For more information, refer to the Salesforce Platform Events documentation.
