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

1059 C<$rank> specifies the effect of the change. If C<$rank>
1060 is 'n', nothing happens. This corresponds to leaving a

1064 If C<$rank> is 'del', the hold request is cancelled.
1066 If C<$rank> is an integer greater than zero, the priority of
1067 the request is set to that value. Since priority != 0 means
1068 that the item is not waiting on the hold shelf, setting the
1069 priority to a non-zero value also sets the request's found
1070 status and waiting date to NULL.
1072 If the hold is 'found' (waiting, in-transit, processing) the
1073 only field that can be updated is the expiration date.
1075 The optional C<$itemnumber> parameter is used only when

1077 of the hold request is set accordingly; if omitted, the itemnumber

1586 This routine adjusts the priority of a hold request and holds
1589 In the first form, where a reserve_id is passed, the priority of the

1591 accordingly. If the rank is "del", the hold is cancelled. If no rank
1592 is supplied, all of the holds on that bib have their priority adjusted
1593 as if the second form had been used.
1595 In the second form, where a biblionumber is passed, the holds on that
1596 bib (that are not captured) are sorted in order of increasing priority,
1597 then have reserves.priority set so that the first non-captured hold
1598 has its priority set to 1, the second non-captured hold has its priority
1599 set to 2, and so forth.
1601 In both cases, holds that have the lowestPriority flag on are have their
1602 priority adjusted to ensure that they remain at the end of the line.

2274 priority is based on the set of holds whose start date falls before
2275 the parameter value.
