Basically the reservation system is extremely basic, there is no reporting, no way to link reservations to a ticket, thus no reporting that way. There are a number of open enhancement requests you may want to take a look at Web Help Desk Feature Requests
Thank you for your information, saves me a lot of additional time searching (after 2 hours yesterday).
I did not read all the posts for Reservations, but it seems that nobody was asking for reporting. I thought it would be very useful to find out effect fullness of the service provided and potential needs for amendments.
Maybe I put in a suggestion for change.
