In order to get access to your reservation, you should simply click on Reservations in the Control Panel's menu.
As soon as you open the Reservations Page you will be able to see the reservations that you have received during the last week. You may easily change the settings to see the list of reservations that you prefer.
You can sort the reservation lists by Status (Confirmed, Cancelled, Modified), Reservation Source (Direct, Booking.com, Expedia, etc), Text Search (search any text that is included in the reservation, such as Name or City) or Rate Plan.
Also, you can set the date period that you prefer depending on the Check-In date, Check-Out date, Modification date or Creation date.
If your package includes Channel Manager functionality, then you can see all the reservations from all the Channels in one page.
