53 C4::Reserves - Koha functions for dealing with reservation.
61 This modules provides somes functions to deal with reservations.
63 Reserves are stored in reserves table.
64 The following columns contains important values :
65 - priority >0 : then the reserve is at 1st stage, and not yet affected to any item.
66 =0 : then the reserve is being dealed
67 - found : NULL : means the patron requested the 1st available, and we haven't chosen the item
68 T(ransit) : the reserve is linked to an item but is in transit to the pickup branch
69 W(aiting) : the reserve is linked to an item, is at the pickup branch, and is waiting on the hold shelf
70 F(inished) : the reserve has been completed, and is done
71 P(rocessing) : reserved item has been returned using self-check machine and reserve needs to be confirmed
72 by librarian before notice is send and status changed to waiting.
73 Applicable only if HoldsNeedProcessingSIP system preference is set.
74 - itemnumber : empty : the reserve is still unaffected to an item
75 filled: the reserve is attached to an item
76 The complete workflow is :
77 ==== 1st use case ====
78 patron request a document, 1st available : P >0, F=NULL, I=NULL
79 a library having it run "transfertodo", and clic on the list
80 if there is no transfer to do, the reserve waiting
81 patron can pick it up P =0, F=W, I=filled
82 if there is a transfer to do, write in branchtransfer P =0, F=T, I=filled
83 The pickup library receive the book, it check in P =0, F=W, I=filled
84 The patron borrow the book P =0, F=F, I=filled
86 ==== 2nd use case ====
87 patron requests a document, a given item,
88 If pickup is holding branch P =0, F=W, I=filled
89 If transfer needed, write in branchtransfer P =0, F=T, I=filled
90 The pickup library receive the book, it checks it in P =0, F=W, I=filled
91 The patron borrow the book P =0, F=F, I=filled

775 C<$itemnumber> is the book's item number.
776 C<$lookahead> is the number of days to look in advance for future reserves.
778 As I understand it, C<&CheckReserves> looks for the given item in the
779 reserves. If it is found, that's a match, and C<$status> is set to
782 Otherwise, it finds the most important item in the reserves with the
783 same biblio number as this book (I'm not clear on this) and returns it
784 with C<$status> set to C<Reserved>.
786 C<&CheckReserves> returns a two-element list:
788 C<$status> is either C<Waiting>, C<Reserved> (see above), or 0.
790 C<$reserve> is the reserve item that matched. It is a
791 reference-to-hash whose keys are mostly the fields of the reserves
792 table in the Koha database.

997 is 'n', nothing happens. This corresponds to leaving a
998 request alone when changing its priority in the holds queue
1001 If C<$rank> is 'del', the hold request is cancelled.
1003 If C<$rank> is an integer greater than zero, the priority of
1004 the request is set to that value. Since priority != 0 means
1005 that the item is not waiting on the hold shelf, setting the
1006 priority to a non-zero value also sets the request's found
1007 status and waiting date to NULL.

1570 This routine adjusts the priority of a hold request and holds
1573 In the first form, where a reserve_id is passed, the priority of the
1574 hold is set to supplied rank, and other holds for that bib are adjusted
1575 accordingly. If the rank is "del", the hold is cancelled. If no rank
1576 is supplied, all of the holds on that bib have their priority adjusted
1577 as if the second form had been used.
1579 In the second form, where a biblionumber is passed, the holds on that
1580 bib (that are not captured) are sorted in order of increasing priority,
1581 then have reserves.priority set so that the first non-captured hold
1582 has its priority set to 1, the second non-captured hold has its priority
1583 set to 2, and so forth.
1585 In both cases, holds that have the lowestPriority flag on are have their
1586 priority adjusted to ensure that they remain at the end of the line.

2201 the current system time and that are neither on the hold shelf
2204 The reserve date parameter is optional; if it is supplied, the
2205 priority is based on the set of holds whose start date falls before
2206 the parameter value.
