A system for reconciling a central inventory record having a count of
products and location assignments for the instances of the count chooses
instances for write-ons and write-offs based on the location assignments.
When instances are to be written-on to the inventory record due to a
shortage of instances in the record, then the added instances are
assigned a location by detecting a shortage of instances for a particular
location assignment relative to a proportionate amount and providing that
location assignment to one or more of the added instances. When instances
are to be written-off from the inventory record due to an excess number
of instances in the record, the instances are removed by detecting
excessive instances for a particular location assignment relative to a
proportionate amount and removing one or more instances having that
particular location assignment.
