Device Information Record 
The device information record is an object in the IS-U system that enables the system to perform billing-orientated functions.
When carrying out billing functions, the complete IS-U Device Management (IS-U-DM) does not have to be used. Instead, you can create a device information record that only manages device data required for billing, for example, rate data, device allocations, register relationships and maintenance of logical registers.
There is no longer a connection to Plant Maintenance (PM) . Communication with other systems, such as importing consumption data, takes place via the point of delivery.
