Manage Meter Reading HistoryManage Meter Reading HistoryYou use the Manage Meter Reading History action to view or update historical meter readings. When you update a meter reading, the delta (change) readings are applied to all of the readings for that meter that are more recent than the date on which you make the update. If the meter is on an asset in a hierarchy, the readings for those assets in the hierarchy also are updated. If the meter is for a location that has assets set up to accept the rolldown from their location, the meters for those assets are updated. For more information, see About Updating Meter Readings.
Depending on your security authorization, you might be able to only view historical readings and not update them.
