P09 Cancellation Handling and Fee Determination - Modeling Notes

Date: 2026-05-18

Process intent

Model full cancellation handling: policy eligibility, fee proposal/guest consent, payment capture attempts, refund treatment, and operational cancellation execution.

Participants

• Hotel National Zermatt
  • Reservations
  • Finance
  • Operations / Front Office
• Payment Provider
• Guest

Distinct process behavior

• DMN decision gate for cancellation eligibility and fee/refund levels.
• Separate path when fee is due vs fee-free cancellation.
• Guest negotiation loop:
  • fee proposal sent
  • guest accepts/rejects
• Finance capture logic with fallback:
  • on-file payment attempt
  • alternate payment request
  • retry gate
  • pending-payment outcome if unresolved
• Settlement branch with refund/no-refund merge before cancellation execution.
• Operational close-out (release inventory + notify service partners) before final confirmation.

Right-to-left flows are intentional for retry/rework paths and finance-to-operations merge routing.
