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
