Stock Location History Is Created Behind The Scenes
An asset's stock location history is only maintained if the asset's respective meter type / item type indicates that stock location history is maintained. If stock location is tracked, the system will create stock location history records in the following situations:
• Whenever an asset is installed at a service point, a stock location history record is stored. The stock location is blank on such a record (because the asset is installed at a service point).
• Whenever an asset is removed from a service point, an "installation" stock location history record is stored. The default stock location into which a removed asset is placed is defined on Postal Code Default - Service Defaults.
• Whenever a meter or item is replicated, the operator must indicate the stock location at which the replicated meters / items reside. Refer to Meter Replicator and Item Replicator for more information.
Note: 
If location tracking for an item type or meter type is turned off and then subsequently turned on again, any change in the location of the item / meter during the period in which location tracking is off will not be recorded. This will result in gaps in the asset's location history.
