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

983 Change a hold request's priority or cancel it.
985 C<$rank> specifies the effect of the change. If C<$rank>
986 is 'W' or 'n', nothing happens. This corresponds to leaving a
987 request alone when changing its priority in the holds queue
990 If C<$rank> is 'del', the hold request is cancelled.
992 If C<$rank> is an integer greater than zero, the priority of
993 the request is set to that value. Since priority != 0 means
994 that the item is not waiting on the hold shelf, setting the
995 priority to a non-zero value also sets the request's found
996 status and waiting date to NULL.
998 The optional C<$itemnumber> parameter is used only when
999 C<$rank> is a non-zero integer; if supplied, the itemnumber
1000 of the hold request is set accordingly; if omitted, the itemnumber
1003 B<FIXME:> Note that the forgoing can have the effect of causing
1004 item-level hold requests to turn into title-level requests. This
1005 will be fixed once reserves has separate columns for requested
1006 itemnumber and supplying itemnumber.

1775 This increments the priority of all reserves after the one
1776 with either the lowest date after C<$reservedate>
1777 or the lowest priority after C<$priority>.
1779 It effectively makes room for a new reserve to be inserted with a certain
1780 priority, which is returned.
1782 This is most useful when the reservedate can be set by the user. It allows
1783 the new reserve to be placed before other reserves that have a later
1784 reservedate. Since priority also is set by the form in reserves/request.pl
1785 the sub accounts for that too.
