Reservations Inventory alters the UI provided by Reservations breaking the Reservable items up into multiple inventories. For example, it you are a Community Media organization, you may have equipment available to a Youth Program, Community Producers, and Internal Productions. Instead of staff seeing all equipment when requesting a reservation or seeing all reservations when checking a producer in or out, each UI is limited to only THAT inventory. This could also be use to divide inventories between multiple locations.
The Inventory submodule for the Reservations API was specifically written for MNN, but has been committed to Drupal.org for other stations to use.
Re-order the inventory blocks by adjusting the order of the taxonomy term order for the reservations_inventory taxonomy.
Structure → Taxonomy → Inventory
Disabled blocks by disabling the top level of Menu under Reservations
Structure → Menu → Inventory
After making a change, you must rebuild the menu.
Shortcut → Devel Dashboard → Rebuild menus
So even if stations only separated their inventory into Studio and Field inventories, it would give them simpler UIs for making reservations as well as checkin out/in reservations.
