It would be logical if and when a customer is making changes to their reservation, but when a Property Manager is making changes, on the back end, surely there should be prompts asking the editor if they wish to keep existing order and payment detail or adjust order detail to the changed property rate and/or dates? This seems logical to me. If you have multiple leads adjusting reservations for unforeseen circumstances and no warning prompt appears to the property manager when making changes, accounting's books would be a disaster.
