When a device specialist identifies the need for new devices, like 100 double-rate electricity meters, they move on to set up a new device category, a new material and register group if needed.
The following figure illustrates the lifecycle of IS-U devices with full logistics integration.

The device specialist is also responsible for creating a purchase requisition for this new material. Upon completion, the purchasing organization then changes this purchase requisition into a purchase order and forwards it to the respective supplier. Upon the delivery of the new devices, these arrive at the warehouse of the utility company.
Once the devices arrive, a warehouse clerk enters goods receipt for the purchase order, stores the devices at the fulfillment storage location. Simultaneously, automatic creation of 100 new device master records occurs. These records are serialized and possesses additional IS-U data which is linked to the new device category. In turn, these devices inherit the register group from the device category.
If the devices have been assigned to a technician for installations, the warehouse clerk posts a stock transfer to a van stock. This is followed by the technician's installation of the device at the customer site and confirmation of the installation with the device number, location, date, and meter readings.
Later, a backoffice clerk or an upload program posts this device installation, including the stock transfer to a hypothetical grid storage location. This is necessary because IS-U devices, even after installation, do not exit the utility company's stock. This transaction involves an IS-U-specific movement type U61 to post the stock transfer from equipment status ESTO to status INST with integrated installation.
Throughout their lifecycle, devices might undergo replacements, removals, or modifications. Device Management provides these necessary functions.
Devices are installed technically at device locations (meter operator, distributor), and for billing purposes at utility installations (all market roles). This establishes the technical and billing-related installation structure and is elaborated in the Device Installation lesson.
Topics like yearly periodic meter reading processing for normal meter residential customers are covered in the Meter Reading lesson. Meanwhile, monthly load shape processing of industrial customers with interval meters is explained in the Energy Data Management unit.
Apart from periodic reading for billing, devices may also go through random reading as part of different business transactions. This includes actions like delivery, move-in/out, installation, replacement, modifications, or removal. Such other meter reading reasons are also discussed in the next lessons.
