Introduction: 

As the world of enterprise technology continues to evolve rapidly, businesses are increasingly relying on sophisticated Enterprise Resource Planning (ERP) systems to drive their strategies and operations. Every organisation has their own way of running the business. Therefore, this results in unique pain points specific to the industry or organisation or the business process. While the scope covered by standard SAP applications is vast, there is still a recognised need for customization to precisely address these unique challenges. 

To address these specific industry-specific pain points, SAP introduced SAP Industry Cloud solutions. These solutions are crafted to offer industry-specific functionalities and address the intricate needs of businesses within diverse sectors. These solutions are crafted to offer industry-specific functionalities and address the intricate needs of businesses within diverse sectors. 

But beyond these boundaries, there lies a void space of scope that is not yet covered by SAP Standard application. This brings us to the terms Extension and extensibility.  

Extension and Extensibility: 

In SAP, extension typically refers to adding new functionalities or features to the standard SAP applications to meet specific business needs. Extensions can take various forms, including additional fields, custom reports, or specialized workflows that are not part of the standard SAP offering. Extensions allow organizations to enhance their SAP systems to align more closely with their unique processes and requirements. 

Extensibility, on the other hand, is a broader concept that encompasses the ability of the SAP system to be extended or modified. It represents the system’s inherent flexibility and openness to accommodate changes and enhancements. SAP extensibility allows organizations to adapt their ERP systems without resorting to extensive custom coding or modifications that could complicate future updates and upgrades. 

What is clean core? 

I would like to declare as “clean core” not a system running without any core customization, but rather a system which follows standardized guidelines for all elements of the core. – Sebastian Schroetel (Clean Core demystified: What does it mean and how to achieve it with SAP BTP?) 

Clean means: up-to-date, transparent, unmodified, consistent efficient and cloud compliant 

Core means: the main aspects of an ERP system, namely extensibility, processes, data, integration, and operation. Capabilities of the core depend on the implemented software-stack. 

Therefore, clean core is a system that is as close to standard as possible, while running cloud-complaint extensions and customizations.  

Components of core: 

1. Software Stack: The standard ERP software encompasses a broad spectrum of functionalities and features.
2. Extensibility: Extensibility involves adding functionality to the standard software, addressing organizational needs beyond the standard offerings.
3. Integrations: Integrations facilitate communication between extensions, the standard solution, and other solutions within the ERP system.
4. Data: Data comprises the information stored in the system, including Master data and Transactional data.
5. Processes: Processes represent the series of actions or steps within the system, covering the end-to-end experience of delivering a desired outcome.
6. Operations: Operations involve governance responsibilities for managing the ERP infrastructure effectively.

Why Clean Core?

Agility and Adaptability: A clean core allows organizations to be more agile and adaptable to changes in the business environment. It ensures that the ERP system can be easily upgraded to the latest releases, enabling the adoption of new features, functionalities, and security updates without significant hurdles. 

Efficient Operations: An ERP system with a clean core operates more efficiently. Standardized processes and configurations lead to smoother day-to-day operations, reducing the risk of errors, improving system performance, and enhancing overall productivity. 

Ease of Integration: Clean core principles facilitate seamless integration with other systems and technologies. When the core is standardized, integrations become more straightforward, ensuring that different parts of the IT landscape can work together cohesively. 

Cloud Readiness: As organizations increasingly move towards cloud-based solutions, a clean core is essential for cloud readiness. It ensures that the ERP system can smoothly transition to the cloud, taking advantage of the scalability, flexibility, and innovation offered by cloud platforms. 

Innovation Enablement: A clean core provides a solid foundation for innovation. It allows organizations to adopt and integrate new technologies, such as artificial intelligence, machine learning, and advanced analytics, without the complications arising from a heavily customized and complex core. 

Risk Mitigation: By adhering to clean core principles, organizations mitigate the risks associated with system upgrades, changes in business processes, and the introduction of new technologies. It enhances system resilience, cybersecurity, and overall risk management. 

Cost-Effective Upgrades: Organizations with a clean core can perform system upgrades more cost-effectively. Upgrading a system with minimal customizations requires less effort, resources, and testing, resulting in reduced costs and downtime. 

Achieving a Clean Core:

Maintain Alignment with the Latest Release: Ensure your SAP system is consistently upgraded to the latest release, allowing your organization to benefit from the newest features, security enhancements, and performance improvements. 

Promote Clean Extensions: Establish a robust governance framework to evaluate the necessity of extensions. Clearly define guidelines for proper extension usage, and segregate extensions from the core by exclusively employing released interfaces. 

Ensure Clean Integrations: Develop and adhere to a comprehensive integration strategy, utilizing interfaces that remain stable across upgrades. Implement effective monitoring and error resolution mechanisms for integrations, and prioritize the documentation and active usage of each integration. 

Optimize Operations: Integrate Clean Core principles into the overall concept of day-to-day operations. Regularly plan and review operational aspects, including security authorizations, integrations, and data management, to ensure ongoing efficiency. 

Streamline Data Management: Foster data cleanliness by maintaining consistent and relevant transaction, master, and configuration data. Utilize stable organizational data, such as company codes and purchase organizations, ensuring completeness, correctness, and relevance. 

Enforce Process Efficiency: Define, document, and disseminate individual processes and scenarios. Adhere to defined processes and leverage SAP Best Practices to ensure streamlined and efficient operations in line with Clean Core principles.
