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

858 the request is set to that value. Since priority != 0 means
859 that the item is not waiting on the hold shelf, setting the
860 priority to a non-zero value also sets the request's found
861 status and waiting date to NULL.

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

1723 the new reserve to be placed before other reserves that have a later
