NOTE: The Channel Manager will not process 'Availability' changes for 'Cancel' or 'Modify' status reservations. For modified or cancelled reservations, it is expected that the integrated PMS will pass back 'Availability' changes once the modification or cancellation message has been processed.

Cancellation XML

The cancellation xml structure is mostly identical to a new reservation with the exception of the HotelReservation ResStatus and the presence of the attribute LastModifyDateTime.

...

It is possible that a cancellation only contain the unique identifiers of the reservation to be cancelled. This will only happen if the original reservation was not stored in PmsXchange. The receiving PMS can process the cancellation if it contains the original reservation or it can respons respond with an Error message if the cancellation cannot be processed due to missing information.
