Transit minimum checkin interval setting

Transit minimum checkin interval setting

OK, here's the situation, a copy went away on a week's vacation...

Support for preventing checkin of a copy that was put into transit "too
recently".  The scenario that prompted the development is this:

Copy at Branch A is checked in and put into transit to fill a hold at
Branch B.  The copy is then accidentally checked in at Branch B.
(Imagine a crate of items with a superbarcode gets checked in at
Branch B and the copy in question was presumed to be in that crate).
This puts the item on the holds shelf (assuming a hold transit) at
Branch B and notifies the patrom the item is ready for pickup.
However, the copy is still just embarking from Branch A.

This new setting allows libraries to configure a minimum transit time.
If a copy is put into transit and checked in during the configured
interval, the checkin will return an (overridable) event that prevents
checkin.  If the setting is not configured, this has no affect on
checkin.
