Project Overview

Initial Situation

The impending end of support for SAP IS-U made it imperative for ENNI to modernize its existing billing landscape. At the same time, the system landscape—which had evolved over time—was highly complex, resource-intensive, and made it difficult to quickly adapt to regulatory and technological market requirements. Added to this were increasing pressure to digitize and a shortage of available migration resources.

Vision

ENNI’s goal was a future-proof, flexible SAP S/4HANA Utilities platform that supports both standardization and company-specific customizations. Key objectives:

Protecting SAP Investments Beyond the End of Support
Reducing Operating Costs and Complexity
Accelerating regulatory and technological adjustments

Solution

Arvato Systems implements AEP.EnerS4 as a standardized successor solution for SAP IS-U, based on:

SAP S/4HANA forUtilities based on a master system
RISE-with-SAP/MSP Model
Clean-Core Architecture
Central Master System for Regulatory Updates

The platform offers additional services such as operation, Application Management, Process Support, and Innovation Services.

Our Services

AEP.EnerS4 is based on a central master system in which regulatory requirements, market standards, and technological innovations are continuously refined. As a result, customers benefit from shared synergies and innovations without having to sacrifice individual customization options.
