A Kit in Custody Does Not Go Out on a Booking

Corrections to how a kit is held and released.

Custody and bookings never overlap on a kit

A kit is one physical unit with one holder. From now on a kit in someone's custody cannot be checked out on a booking, and a kit that is checked out cannot be given a custodian, whatever the kit is made of. The Check out button on a booking holding such a kit is disabled with "Some kits in this booking are currently in custody. Release their custody before you can check-out", the Scan to check out drawer lists the kit under a blocker, and the server refuses a request that gets through anyway, from the web or from the Shelf Companion app: "Cannot check out booking. Some kits are in custody: Camera Kit A. Release their custody first or remove them from the booking." Adding the kit to a booking and reserving it stay allowed, because the kit is assumed back by the time the booking goes out.

Before this, check-out looked at the member assets rather than the kit. A quantity-tracked member reading In custody only means some of its units are held, so a kit built only from pooled stock could go out on a booking while its custodian still held it, and then read Checked out with its custody row still attached.

A kit sharing pooled stock is released with its own booking

When a quantity-tracked asset sits in several kits, say one pool of tripods spread across camera kits, and another kit holding units of it was out on its own booking, checking this kit's booking in used to release everything except the kit: the shared tripod still read Checked out through the other kit, and the release took that as this kit still being out. The booking completed and the kit stayed Checked Out with nothing to clear it. The release now judges a kit by its own slices on the booking, so a shared pooled member never holds a kit back. A kit left stuck this way heals itself the next time it goes out and comes back, since a Checked Out kit can still be added to a draft or reserved booking.

Which kits another booking can take

Three more corrections to the same rule, shipped on 7 October:

• A kit still out on an overdue booking is held for every date. Whether another booking held a kit used to be decided by date overlap alone, so once an overdue booking's due date had passed, a kit that never came back looked free for any later booking. It could be reserved and even checked out on two bookings at once. It is now held for every date until it is checked in, the same way overdue pooled stock already was. See One Booking at a Time.
• Scan to check out warns before you submit. A scanned kit that another booking holds is now listed under a blocker while you scan, and Check out assets stays disabled until you remove it, instead of the refusal arriving only at submit.
• Kits sharing pooled stock are no longer hidden from each other. When two kits each take units of the same pool and one of them was reserved, the kit picker's Hide unavailable filter hid the other one too, even with most of the pool free; adding it by scan or from the Shelf Companion app was refused the same way. A kit is now judged by its own units, so the second kit is offered and can be added.
