In the PMS Settings section in RU you have the option to decide what property information you would like to synchronise from your PMS to Rentals United. If you un-tick any of the boxes and click on Save, that property information will no longer be synchronised from your PMS to RU. You will then be able to manually edit that information directly in your Rentals United account.
If there are boxes that are greyed out in the PMS Settings section, this means that your PMS does not push that information to Rentals United. You will have to edit that information directly in Rentals United. To find out more about this for your PMS specifically, please go to your PMS in the Section "Getting Started with PMS" in the Help Desk
