To create a "guided" experience combined with "routing and authorizations," a Platform Administrator should leverage the power of Flow Builder and the Approval Process engine. Flow Builder is used to create the user- facing interface (Screen Flow) that guides the employee through the expense report submission, ensuring all necessary data is collected in a structured way. This replaces a static page layout with a dynamic, step-by-step wizard. Once the data is captured and the record is created, the Flow can automatically submit the record into an Approval Process. The Approval Process then handles the "routing and authorizations" by sending the report to the appropriate manager or director for sign-off. While Quick Actions (Option B) can launch flows, they are a entry point rather than the logic engine itself. Validation Rules (Option A) only prevent errors but do not guide users or route records. Together, Flow and Approvals provide a seamless end-to-end automation for complex business requirements like expense management.
