Device Management is vital for the SAP S/4HANA Logistics integration and overseeing IS-U devices, which form the groundwork for billing. Work Management contributes to the SAP S/4HANA Service integration of specific IS-U maintenance processes and services. Meter Reading is responsible for scheduling and computing both sporadic and regular meter reading results.
The first phase of the Meter-to-Cash process (M2C) in SAP S/4HANA Utilities is to gather regular meter reading results for billing.
When it comes to billing, the supplier is only required to manage data relevant to billing such as the serial number, rate data, billing factor, and the results of the meter reading. To accomplish this, 'device info records' are used instead of actual devices as they don't contain technical specifications.
meter operator in Germany and distributors in other countries handle data relevant to both billing and technical specifics. They use real devices, supplemented with technical data such as storage location and the actual location of the device for this process.
Device Management supports the SAP S/4HANA Logistics integration and the management of IS-U devices as the basis for billing.
When an IS-U device category is formed, it simultaneously establishes a material with an identical number in Material Management (MM). This device category incorporates IS-U-specific details such as the register group along with MM-specific data, for instance, the price of the material. The device category collects and consolidates the data from various devices of the same type, making it a necessary step for the fabrication of devices.
The inception of an IS-U device leads to the concurrent creation of equipment with a similar serial number in Plant Maintenance (PM). The device houses IS-U-specific data, such as the meter reading results, and PM-specific information, such as the location of equipment. The process of installation sets the device technically into the IS-U device location, which aligns with a PM functional location. From a billing perspective, the device is initiated into the utility installation, which is exclusively an IS-U data relic.
Device Management covers IS-U-specific data and functions, which go beyond the standard Logistics:
- Device Technology defines the billing-relevant register groups (electricity, gas, water, heat) and winding groups.
- Device Installation controls the technical and billing-related installation as well as rate data maintenance in the installation structure.
- Device Inspection controls the sampling procedure, the periodic replacement and the generation of work orders for the replacement devices.
Material Management enables the purchasing and inventory management of IS-U devices.
Work Management generates internal work orders in PM and external work orders in CS to execute IS-U-specific technical processes.
Meter Reading supports the organization and processing of periodic and aperiodic meter reading result determination.
Meter Reading is a pure IS-U function without integration into other SAP components.
