About Updating Meter Readings About Updating Meter Readings When you update the history of a meter using the Manage Meter Reading History action, or insert a historical reading via the Enter Meter Readings action, the following rules are applied to updating the data:
If you enter a modified reading for an asset or location, the change is applied to all delta (change) readings for that meter that are more recent than the date of the modified meter reading. Subsequent meter readings are updated until the first actual reading is reached.
The system only updates meter readings of meters and assets (those assets that were set up to inherit meter readings from parents) that were members of the hierarchy at the time of the original meter reading. Meters and assets added to the hierarchy after the original meter reading remain unchanged.
When a reading is modified, the modified date, user, and a reason for the change is also recorded.
An historical reading can be greater than a subsequent reading only if the meter has a rollover point.
