When Options expire in Booking Manager they change the status to Expired options, but this change in status does not free the boat for a given period so the expired options have to be deleted manually.
The reservations differ according to reservation type. Usually they are of 2 types. Classic is the reservation opened in local LBM and Internet, which are reservations that entered the system online.
If there is a large volume of options it can be an everyday job to delete all expired ones.
This is why the system has the option to delete expired options automatically and it can be set do delete them according to reservation type.
Setting the automatic deletion
From Booking Manager main screen open Preferences > Reservation settings > Online (1.).
Here you will find 2 checks. First one, Delete expired options on web (2.) when checked deletes automatically options that were created online (reservation type Internet). Second one, Delete expired options on LBM (3.) when checked deletes automatically options that were created locally in the system (reservation type Classic).
Default setting for system when it is installed it that it automatically deleted options on Web, but not on LBM.
You can set the Time Period for deleting expired options (4.). Default time is set to 00:00, but can be set at 04:00, 08:00, 12:00, 16:00 or 20:00.
Press Apply when done (5.).
