PoweredPNR  Cancel

The PoweredPNR/Cancel function works with the functionality of Amadeus PNR.

The function Cancel is used to specific actions to be processed on a PNR such as identifying the PNR elements and sub elements that need to be cancelled.  

You cannot cancel or delete itinerary flight segments that are marked as flown, or
auxiliary segments that are marked as past, from a PNR.
