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

911 Find a book in the reserves.
913 C<$itemnumber> is the book's item number.
914 C<$lookahead> is the number of days to look in advance for future reserves.
916 As I understand it, C<&CheckReserves> looks for the given item in the
917 reserves. If it is found, that's a match, and C<$status> is set to
920 Otherwise, it finds the most important item in the reserves with the
921 same biblio number as this book (I'm not clear on this) and returns it
922 with C<$status> set to C<Reserved>.
924 C<&CheckReserves> returns a two-element list:
926 C<$status> is either C<Waiting>, C<Reserved> (see above), or 0.
928 C<$reserve> is the reserve item that matched. It is a
929 reference-to-hash whose keys are mostly the fields of the reserves
930 table in the Koha database.

1786 This routine adjusts the priority of a hold request and holds
1789 In the first form, where a reserve_id is passed, the priority of the
1790 hold is set to supplied rank, and other holds for that bib are adjusted
1791 accordingly. If the rank is "del", the hold is cancelled. If no rank
1792 is supplied, all of the holds on that bib have their priority adjusted
1793 as if the second form had been used.
1795 In the second form, where a biblionumber is passed, the holds on that
1796 bib (that are not captured) are sorted in order of increasing priority,
1797 then have reserves.priority set so that the first non-captured hold
1798 has its priority set to 1, the second non-captured hold has its priority
1799 set to 2, and so forth.
1801 In both cases, holds that have the lowestPriority flag on are have their
1802 priority adjusted to ensure that they remain at the end of the line.

2465 Calculate priority for a new reserve on biblionumber, placing it at
2466 the end of the line of all holds whose start date falls before
2467 the current system time and that are neither on the hold shelf
2470 The reserve date parameter is optional; if it is supplied, the
2471 priority is based on the set of holds whose start date falls before
2472 the parameter value.
2474 After calculation of this priority, it is recommended to call
2475 _ShiftPriorityByDateAndPriority. Note that this is currently done in
