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

1564 This routine adjusts the priority of a hold request and holds
1567 In the first form, where a reserve_id is passed, the priority of the
1568 hold is set to supplied rank, and other holds for that bib are adjusted
1569 accordingly. If the rank is "del", the hold is cancelled. If no rank
1570 is supplied, all of the holds on that bib have their priority adjusted
1571 as if the second form had been used.
1573 In the second form, where a biblionumber is passed, the holds on that
1574 bib (that are not captured) are sorted in order of increasing priority,
1575 then have reserves.priority set so that the first non-captured hold
1576 has its priority set to 1, the second non-captured hold has its priority
1577 set to 2, and so forth.
1579 In both cases, holds that have the lowestPriority flag on are have their
1580 priority adjusted to ensure that they remain at the end of the line.
