Updating historical meter readings

Use the Assets application to update the history of a meter or to insert a historical reading.

The following rules apply to updating historical meter readings:

• If you specify a modified reading for an asset or for a location, the change is applied to all delta (change) readings that are more recent than the date of the modified reading for that meter. Subsequent meter readings are updated until the first actual reading is reached.
• Only readings of meters and of 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 are updated. Meters and assets added to the hierarchy after the original meter reading remain unchanged.
• When a reading is modified, the modified date, the user, and a reason for the change is recorded.
• A historical reading can be greater than a subsequent reading only if the meter has a rollover point.
