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

984 Change a hold request's priority or cancel it.
986 C<$rank> specifies the effect of the change. If C<$rank>
987 is 'W' or 'n', nothing happens. This corresponds to leaving a
988 request alone when changing its priority in the holds queue
991 If C<$rank> is 'del', the hold request is cancelled.
993 If C<$rank> is an integer greater than zero, the priority of
994 the request is set to that value. Since priority != 0 means
995 that the item is not waiting on the hold shelf, setting the
996 priority to a non-zero value also sets the request's found
997 status and waiting date to NULL.
999 The optional C<$itemnumber> parameter is used only when
1000 C<$rank> is a non-zero integer; if supplied, the itemnumber
1001 of the hold request is set accordingly; if omitted, the itemnumber
1004 B<FIXME:> Note that the forgoing can have the effect of causing
1005 item-level hold requests to turn into title-level requests. This
1006 will be fixed once reserves has separate columns for requested
1007 itemnumber and supplying itemnumber.

1776 This increments the priority of all reserves after the one
1777 with either the lowest date after C<$reservedate>
1778 or the lowest priority after C<$priority>.
1780 It effectively makes room for a new reserve to be inserted with a certain
1781 priority, which is returned.
1783 This is most useful when the reservedate can be set by the user. It allows
1784 the new reserve to be placed before other reserves that have a later
1785 reservedate. Since priority also is set by the form in reserves/request.pl
1786 the sub accounts for that too.
