Canceling/Deleting a Travel Service (Travel Manager) 
Use
Depending on the reservation status of the flights, hotel rooms, car rentals and rail trips you can cancel or simply delete items from the travel plan.
You can simply delete request items with the status open, that is, items for which you have not yet made an exact service selection or booking.
Once a travel service has been selected or booked you must cancel this and confirm the cancellation so that it can be transferred to the connected reservation system.
You can cancel car rental and flight reservations at any time, as long as no ticket has been issued. Only after a ticket has been issued can possible cancellation fees be incurred. You can find out about these from the responsible travel agency.
If you have opened a travel plan in editing mode, you will find information here about the cancellation and rebooking conditions of the travel services booked.
