+This modules provides somes functions to deal with reservations.
+
Reserves are stored in reserves table.
The following columns contains important values :
- priority >0 : then the reserve is at 1st stage, and not yet affected to any item.
=0 : then the reserve is being dealed
- found : NULL : means the patron requested the 1st available, and we haven't choosen the item
- W(aiting) : the reserve has an itemnumber affected, and is on the way
+ T(ransit) : the reserve is linked to an item but is in transit to the pickup branch
+ W(aiting) : the reserve is linked to an item, is at the pickup branch, and is waiting on the hold shelf
F(inished) : the reserve has been completed, and is done
- itemnumber : empty : the reserve is still unaffected to an item
filled: the reserve is attached to an item
a library having it run "transfertodo", and clic on the list
if there is no transfer to do, the reserve waiting
patron can pick it up P =0, F=W, I=filled
- if there is a transfer to do, write in branchtransfer P =0, F=NULL, I=filled
+ if there is a transfer to do, write in branchtransfer P =0, F=T, I=filled
The pickup library recieve the book, it check in P =0, F=W, I=filled
The patron borrow the book P =0, F=F, I=filled
==== 2nd use case ====
patron requests a document, a given item,
If pickup is holding branch P =0, F=W, I=filled
- If transfer needed, write in branchtransfer P =0, F=NULL, I=filled
- The pickup library recieve the book, it checks it in P =0, F=W, I=filled
+ If transfer needed, write in branchtransfer P =0, F=T, I=filled
+ The pickup library receive the book, it checks it in P =0, F=W, I=filled
The patron borrow the book P =0, F=F, I=filled
