The system watches for the inventory level of items in the catalog to drop below a given value.
Technical note: This element is triggered when the ScenarioManager receives an InventoryThresholdReached message sent by the InventoryManager. This message indicates that the stockLevel value for the specific item has dropped below the stockThreshold value (or the backorderLevel value is less than backorderThreshold, or preorderLevel is below preorderThreshold). For more information, see the Inventory Framework chapter in the ATG Commerce Programming Guide.
