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

1752 It effectively makes room for a new reserve to be inserted with a certain
1753 priority, which is returned.
1755 This is most useful when the reservedate can be set by the user. It allows
1756 the new reserve to be placed before other reserves that have a later
1757 reservedate. Since priority also is set by the form in reserves/request.pl
