This means that, if you are in a monthly view you will only update for that month, if you are in a 2 month view you will updates for those 2 months and in Year view for the whole year - except for dates in the past. This synchronize can be made from All Channels or for each channel individually, but not for All Rooms. **ATTENTION:** - Siteminder's channels can also be synchronized, however due to a technical constraint, Booking and Expedia are the only ones that we can check availabilities, for other channels we can only update. Hoteliers can always check the availability updates for Siteminder's channels on Log history or Log analysis - If hoteliers have allotments on channels, the availability won't read them - So it can be showing 0 availability when in reality hoteliers may still have availability on allotment - [Self Service Portal](http://support.guestcentric.com) - [Accounting - Billing Information](https://www.guestcentric.com/payment-methods) - [Contact Us](https://www.guestcentric.com/contact-us) - [Log-In](https://login-emea01.guestcentric.net) [Guestcentric](//www.guestcentric.com/) - [About us](//www.guestcentric.com/about-us/) - [Blog](//www.guestcentric.com/blog/) - [Billing Information](//www.guestcentric.com/billing-information/) - [Terms of use](//www.guestcentric.com/terms-of-use/) - [Newsletter Sign Up](//www.guestcentric.com/contact-us/newsletter-signup/) **UNITED STATES** **San Diego** 7752 Fay Ave, Suite L La Jolla, San Diego, CA 92037 T. +1 (858) 900 2400 **New York** 104 West 40th Street, Suite 400 New York, NY 10018 T. +1 (858) 900 2400 **PORTUGAL** **Lisbon** Avenida Jose Gomes Ferreira 9 Miraflores 1495-139 Lisboa T.
