https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=40644 --- Comment #1 from Pedro Amorim <pedro.amorim@openfifth.co.uk> --- Created attachment 185358 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=185358&action=edit Bug 40644: Only count checkouts that have not yet been counted as bookings Test plan: 1) Have a record with 8 items. 2) Place a booking on 6 of the items (6 bookings total) for a full month (e.g. August) 3) Check-out all 6 of those bookings 4) Attempt to place a new booking for one of the 2 free items. 5) It will fail with error "Booking conflicts". This is because the code is adding 6 checkouts with 6 bookings = 12 which is higher than 8 bookable items. 6) With this patch, check-outs that refer to an existing booking are excluded, so the check becomes if 8 - 6 > 0 (which passes the check) rather than 8 - 12 > 0 (which fails the check) -- You are receiving this mail because: You are the assignee for the bug.
