Clean core is a transformation journey that helps ensure organizations use the latest release, minimize modifications, and run with cloud-compliant extensions and customizations.
Clean core gives ERP the flexibility to adapt to changing business requirements with modular innovation, which SAP defines as the ability to build innovative extensions and functionality decoupled from the core and cloud-ready.

The Value of a Clean Core
Why is a clean core important?
The business case for adopting a clean core approach with SAP cloud ERP revolves around the following key points:
- Standardization of Processes
With the transition to SAP S/4HANA, SAP has undertaken a significant effort to simplify and standardize its ERP software. By removing redundant functionalities and simplifying data models, SAP aims to create a cleaner, more efficient core system. A clean core ensures that standard processes are maintained without heavy customizations. This standardization can lead to reduced complexity in business operations, which in turn can lower costs, decrease risk, and improve efficiency. For instance, in previous versions of SAP ERP, there were often multiple ways to perform the same task, leading to complexity and confusion for users. With SAP cloud ERP, SAP has consolidated and standardized these processes, reducing complexity, and improving usability.
- Seamless Integration and Extensibility
A clean core supports seamless integration with other cloud solutions, such as those offered by SAP's ecosystem, enabling a more connected enterprise without the compatibility issues that can arise with heavy customizations.
- Flexibility
A clean core allows businesses to be more agile. With fewer customizations, the system is easier to update and upgrade. This agility means businesses can quickly adapt to market changes, regulatory requirements, or technological advancements.
- Scalability
Businesses can scale more effectively with a standardized system. A clean core can handle increasing volumes of transactions without the need for significant additional custom development or infrastructure.
- High Performance
The clean core approach takes full advantage of SAP S/4HANA's in-memory database, which can dramatically improve the performance of business processes and analytics. In addition, SAP has focused on eliminating legacy code and outdated functionality that is no longer relevant or necessary for modern business processes. This approach not only reduces the size and complexity of the software, but also improves performance and scalability.
- Innovation Ability and Adoption
SAP cloud ERP with a clean core approach, facilitates faster innovation. SAP continuously delivers new functionalities and improvements, including artificial intelligence, embedded analytics, and automated processes. These can be deployed rapidly due to the reduced complexity of the core system.
With a clean core, businesses can shift their focus from maintaining customizations to innovating and improving business processes. This means resources can be allocated to activities that add more value to the business.
- Security, Compliance and Privacy Controls
With standard processes, compliance with industry standards and regulations is easier to achieve and maintain, as the core system is designed to be compliant with current standards, reducing the compliance burden on the organization.
Standard processes are well-tested and supported, which reduces the risk of business disruption and ensures that critical business functions are always available and reliable
- Lower Total Cost of Ownership (TCO)
By minimizing customization, companies can reduce the cost of maintaining their ERP systems. This includes lower costs for upgrades, testing, and support, resulting in a lower total cost of ownership over the life of the system.
SAP's Clean Core Strategy
A clean core is a system that is as close to standard as possible, while running cloud-compliant extensions and customizations.
It allows companies to adapt their system to changing business needs and adopt new capabilities.
The core of ERP software consists of six fundamental dimensions: software stack, extensibility, integrations, processes, data, and operations.

With a clean core, the performance of each ERP dimension improves.
Overall, SAP's clean core strategy in SAP S/4HANA exemplifies its commitment to simplification and innovation.
