Reserves are stored in reserves table. The following columns contains important values : - priority >0 : then the reserve is at 1st stage, and not yet affected to any item. =0 : then the reserve is being dealed - found : NULL : means the patron requested the 1st available, and we haven't chosen the item T(ransit) : the reserve is linked to an item but is in transit to the pickup branch W(aiting) : the reserve is linked to an item, is at the pickup branch, and is waiting on the hold shelf F(inished) : the reserve has been completed, and is done P(rocessing) : reserved item has been returned using self-check machine and reserve needs to be confirmed by librarian before notice is send and status changed to waiting. Applicable only if HoldsNeedProcessingSIP system preference is set. - itemnumber : empty : the reserve is still unaffected to an item filled: the reserve is attached to an item The complete workflow is : ==== 1st use case ==== patron request a document, 1st available : P >0, F=NULL, I=NULL a library having it run "transfertodo", and clic on the list if there is no transfer to do, the reserve waiting patron can pick it up P =0, F=W, I=filled if there is a transfer to do, write in branchtransfer P =0, F=T, I=filled The pickup library receive the book, it check in P =0, F=W, I=filled The patron borrow the book P =0, F=F, I=filled ==== 2nd use case ==== patron requests a document, a given item, If pickup is holding branch P =0, F=W, I=filled If transfer needed, write in branchtransfer P =0, F=T, I=filled The pickup library receive the book, it checks it in P =0, F=W, I=filled The patron borrow the book P =0, F=F, I=filled =head1 FUNCTIONS =cut our (@ISA, @EXPORT_OK); BEGIN { require Exporter; @ISA = qw(Exporter); @EXPORT_OK = qw( AddReserve GetReserveStatus ChargeReserveFee GetReserveFee ModReserveAffect ModReserve ModReserveStatus ModReserveCancelAll ModReserveMinusPriority MoveReserve CheckReserves CanBookBeReserved CanItemBeReserved CanReserveBeCanceledFromOpac CancelExpiredReserves AutoUnsuspendReserves IsAvailableForItemLevelRequest ItemsAnyAvailableAndNotRestricted AlterPriority ToggleLowestPriority ReserveSlip ToggleSuspend SuspendAll CalculatePriority IsItemOnHoldAndFound GetMaxPatronHoldsForRecord MergeHolds RevertWaitingStatus ); } =head2 AddReserve AddReserve( { branchcode => $branchcode, borrowernumber => $borrowernumber, biblionumber => $biblionumber, priority => $priority, reservation_date => $reservation_date, expiration_date => $expiration_date, notes => $notes, title => $title, itemnumber => $itemnumber, found => $found, itemtype => $itemtype, item_group_id => $item_group_id } ); Adds reserve and generates HOLDPLACED message and HOLDPLACED_PATRON message.

C<$rank> specifies the effect of the change. If C<$rank> is 'n', nothing happens. This corresponds to leaving a request alone when changing its priority in the holds queue for a bib. If C<$rank> is 'del', the hold request is cancelled. If C<$rank> is an integer greater than zero, the priority of the request is set to that value. Since priority != 0 means that the item is not waiting on the hold shelf, setting the priority to a non-zero value also sets the request's found status and waiting date to NULL. If the hold is 'found' (waiting, in-transit, processing) the only field that can be updated is the expiration date. The optional C<$itemnumber> parameter is used only when C<$rank> is a non-zero integer; if supplied, the itemnumber of the hold request is set accordingly; if omitted, the itemnumber is cleared.
