The maintenance history contains important object-related technical data. This means that it contains information for each object on,

• the causes of these malfunctions
• what findings were to be noted, and
• what maintenance activities were performed

The maintenance notifications form the basis of the notification history. Technical maintenance data can only be stored for long periods of time if maintenance notifications are used.
