Currently, with local holds priority enabled the holds queue will always target an available local item if one exists; this preference is enforced before Koha consults the transport cost matrix or thinks about the Hungarian algorithm. This dev will: - add a new field to tmp_holdsqueue: local priority match - add a new system preference to enable this option and set days value for local priority period - local priority period is defined relative to when the hold was created - when the queue targets an item, add the local priority match flag if the target item is within the local holds group of the hold pickup location - at checkin, if the item could fill a hold Koha will check: -- is this item within the hold pickup group? If yes, fill hold; if no, proceed to next check -- is the hold within the local priority period? If no, fill hold; if yes, proceed to next check -- does the queue's current target have the local priority match flag? If no, fill hold; if yes, do not fill hold (look for other holds this item could fill or check item in)
