Status Transitions — CAP Best Practices

Primary reference: https://cap.cloud.sap/docs/releases/nov25
Status-Transition Flows: https://cap.cloud.sap/docs/guides/services/status-flows
Note: Status-Transition Flows are Gamma status as of CAP December 2025 — production ready in cds 9.5+

Option A: @flow annotations (Gamma status, cds 9.5+ — zero boilerplate)

Define state machines directly in CDS with @flow:

using { cuid, managed } from '@sap/cds/common';

type TravelStatus : String enum {
  Open     = 'O';
  Accepted = 'A';
  Canceled = 'C';
}
