Northern Trail Outfitters wants to initiate expense reports from Salesforce to the external HR system.

To meet the requirement of a " review process " that ends with data being sent to an " external system, " the administrator needs Approval Processes and Outbound Messages. The Approval Process (Option D) handles the internal workflow, ensuring that the manager and director sign off on the expense report. Once the final approval is granted, an " Approval Action " can be triggered. The administrator should use an Outbound Message (Option A) as that action. Outbound Messages are designed to send specific record data (XML via API) to an external URL whenever a record change occurs. This provides a reliable, declarative way to integrate Salesforce with an HR system. Quick Actions (Option C) and Email Alerts (Option B) do not support the technical data transfer needed for external system integration.
