A Platform Administrator needs to configure an approval process for the sales team when opportunities...

The fundamental way to control which records enter an Approval Process is by defining Entry Criteria. During the setup of an approval process, the administrator specifies field-level conditions (e.g., Amount > 50,000 AND Stage = Closed Won) that a record must meet to be eligible for approval. If a user attempts to submit a record that does not meet these criteria, Salesforce will display an error message and prevent the process from starting. This ensures that the finance or management teams are only notified of deals that actually require their sign-off. While a Screen Flow (Option C) could be used to launch the process, the entry criteria within the approval process itself act as the ultimate " gatekeeper " for the automation. Validation rules (Option D) prevent bad data but do not route records for approval. Dynamic Forms (Option B) can show or hide the " Submit for Approval " button, but they do not enforce the underlying business logic of the process itself.
