How to make the first resource unavailable, when the second related resource is reserved?

You can block the availability of one resource when another resource is reserved. To do this, select the blocking resources in the settings of the target resource.

By default, the blocking resource will occupy the same number of shares in the main resource as are reserved in the blocking resource. For example, if 5 seats are reserved in the blocking resource, then 5 seats will also be blocked in the main resource. If you use the price option for the Whole resource, the reservation will occupy all shares of the main resource.

You can adjust these settings. Open the blocking resource menu.

Then select either Whole resource or Fixed number.

If you select Whole resource, then booking any number of shares in the blocking resource will block all shares in the main resource.

If you select Fixed number, for example 3, then booking any number of shares in the blocking resource will block exactly 3 shares in the main resource.

In these cases, reservations are not duplicated. If you cancel the order in the blocking resource, the time will be immediately unblocked in the main resource.

In this way, resources can mutually block each other. Resource types and their schedules do not need to match.
