In case your PMS can send to BEONx the daily inventory it will be loaded directly to your RMS. So when you update the inventory in the PMS (blocked spaces, out of service, etc) the RMS will update it automatically.

In order to have a good connection between your PMS and your RMS, check how to map your espaces with the PMS and the Channel Manager.

In case you have any doubt, ask your Customer experience team.
