How to control patrons and circulation?
Settings for controlling circulation and patron information.
The Transport cost matrix lets a library system define relative costs to transport books to one another. In order for the system to use this matrix you must first set the UseTransportCostMatrix preference to 'Use'.
The Transport cost matrix takes precedence in controlling where holds are filled from, if the matrix is not used then Koha checks the StaticHoldsQueueWeight.
Costs are decimal values between some arbitrary maximum value (e.g. 1 or 100) and 0 which is the minimum (no) cost. For example, you could just use the distance between each library in miles as your 'cost', if that would accurately reflect the cost of transferring them. Perhaps post offices would be a better measure. Libraries sharing a post office would have a cost of 1, adjacent post offices would have a cost of 2, etc.
To enter transport costs simply click in the cell you would like to alter, uncheck the 'Disable' box and enter your 'cost'
After entering in your cost, hit 'Enter' on your keyboard or click the 'Save' button at the bottom of the matrix to save your changes.
A NULL value will make no difference where the From and To libraries are the same library. However, as a best practice, you should put a 0 in there. For all other To/From combinations, a NULL value will cause that relationship to act as if it has been disabled. So, in summary, don't leave any of the values empty. It's best to always put a number in there ( even if you choose to disable that given To/From option ).
