If you want to offer your inventory in bundles or if any of your inventory options share resources (rentals, staff, vehicles, etc) with other, overlapping options, you can link their availability. Options with linked availability won't allow more than a set number of spaces to be booked between them.
The Link Availability action needs to be used with the Inventory Item condition so that you can select all the options that need to be linked. If you don't set any Inventory Item conditions then your entire inventory's availability will be linked.
To create a rule that uses the Link Availability action, follow these steps:
1. Navigate to Inventory > Rules in the main menu.
2. Click Create Rule.
3. Give your rule a name that's easy to recognize, and a description of what it will do.
4. Click Add New Condition.
5. Click Inventory being booked is...
6. Select the options you want to link.
7. Click Add New Action.
8. Click Link Availability in the THEN window.
9. Enter the maximum number of spaces that should be shared between all included inventory.
11. Click Create Rule.
