Some of the fields in creating a reordering rule are not obvious.
- There is a field for the Warehouse. The definition of a warehouse includes 3 location fields. In addition to this warehouse, there is also a location field in the rule. 
- What's the difference between the locations in the warehouse and the location in the rule? 
- What does Quantity Multiple mean and do?
- What is the unit of measure used in the Max/Min field? The one in the rule (below the warehouse rule)?
