After completing this lesson, you will be able to keep landscapes reliable and flexible in a clean core compliant way

Clean Core - Integration

Keep The Landscape Reliable And Flexible
Clean core Mantra: Keep the landscape reliable and flexible.

So far, we have looked at three principles of clean core, business processes, extensions, and data. We now turn our attention to the integration principle. By "integration" we refer to the total of different systems that enterprises use for different purposes, and the inevitable necessary integrations between them. Clean core matters here as much as it does in the other principles. "Keep the landscape flexible and reliable" is the mantra for the integration principle. In this lesson, we see how to do this.

A clean core system ensures upgrade stability through SAP standard integration scenarios. It accelerates innovation via API-led strategy and event-driven architecture, while SAP expert monitoring and a centralized end-to-end monitoring tool help reduce operational risk. With strong governance and by applying the SAP Integration Advisory Methodology, customers can build a robust, reliable, and future-ready integration strategy grounded in SAP Best Practices and modern SAP integration tools.

SAP standard integrations are security-compliant, current, and easily extensible. While custom integrations can be used, choosing standard options minimizes upgrade risk and keeps operations smooth. It is advisable to adopt the latest integration technologies where feasible, although in certain situations, using tried-and-tested methods such as IDocs might still be recommended.

Key benefits for customers using SAP standard integrations include:

  • Seamless upgrades with stable and compatible functionality.
  • Access to ongoing innovation from SAP.
  • Optimized operations reduce total cost of ownership (TCO).
  • Lower development costs (TCD) as integrations are built by SAP.
  • Assurance of security and compliance with current standards.
  • Increased agility in introducing new integrations.

SAP Business Accelerator Hub provides SAP's model company for SAP Business Suite and scenario's enabling SAP standard extension points. If required, customers can easily adapt the model company for SAP Business Suite to their customer needs within the scope of the extension options provided by SAP. This should be done without modification by leveraging released APIs.

It should be ensured that the interfaces are used according to their character — e.g. avoiding using transactional interfaces for mass replication—and ensure all integrations are actively utilized. If no SAP integration or released API exists, the required integration should be made a requirement to SAP.

What Is Clean Integration

Clean Integration Principle

To achieve a clean and efficient integration with SAP, it's essential to focus on several key value drivers and establish a strategic approach that ensures seamless operations, cost-effectiveness, and ongoing innovation. Here's a detailed summary of how these elements can be combined:

Core Value Drivers for Integration

  • Seamless Upgrades: Ensure stable and compatible functionality with SAP solutions to facilitate effortless upgrades. This reduces disruptions and maintains operational continuity.
  • Access to Ongoing Innovation: Leverage SAP’s continual innovation to stay ahead in technology adoption. This improves the ability to integrate future advancements seamlessly.
  • Optimized Operations: By adopting efficient integration strategies, reduce the Total Cost of Ownership (TCO), thereby maximizing operational efficiency and cost savings.
  • Minimize Operational Risks: Implement systems that ensure seamless integration, which keeps business processes running smoothly and reduces associated risks.
  • Lower Development Costs (TCD): Utilize SAP-built integrations to cut down development costs significantly. A consistent decision-making process further contributes to reduced TCD.
  • SAP Model Company For SAP Business Suite: Use standardized integration content offered by SAP to streamline processes, cutting both TCD and TCO.
  • Transparency and Reusability: Promote transparency in integration processes and encourage reusability of components, which helps in reducing TCD and TCO.
  • Security and Compliance: Maintain assurance of security and compliance with current standards, safeguarding against potential vulnerabilities.
  • Enhanced Agility: Increase agility in introducing new integrations by adopting modern, flexible integration technologies.

SAP Integration Solution Advisory Methodology (SAP ISA-M)

Defining a target integration architecture that incorporates clean core principles and modern integration technologies is crucial for every customer. This architecture should guide the organization in its transformation journey towards a future-state. SAP recommends using the SAP Integration Solution Advisory Methodology (SAP ISA-M) for strategic assessment. A robust strategy begins with full transparency over current integrations, understanding technical debt, and assessing migration efforts to develop a cleaner, more efficient system. Continuous modernization, through adopting paradigms like central middleware layers, API-led integration, and Event-Driven Architecture (EDA), is key to maintaining reliability and flexibility amidst rapid technological changes. Governance plays a critical role, and establishing a Center of Excellence (CoE) with "get clean, stay clean" processes ensures consistent application of integration principles, supporting scalability, quality, and compliance. Each activity contributes independently to enhancing the integration landscape.

Achieving Clean Integrations

How To Achieve Clean Integrations

Achieving clean integrations will revolve around the following techniques:

Unlock Agility And Innovation With A Future-Ready integration Strategy

Develop a comprehensive integration strategy using the SAP Integration Solution Advisory Methodology, aiming for a future-state architecture that incorporates cloud-native, API-first, and event-driven frameworks. This strategy includes establishing robust governance processes to ensure adherence to standards and consistency, minimizing technical debt. Regular architecture reviews should align technological evolution with business objectives, integrating governance within project lifecycles, and evolving governance models based on feedback. These actions enhance agility and innovation, allowing businesses to adapt swiftly to changing needs and technology trends.

Accelerate Productivity And Efficiency With Best Practices And Modern Technologies

Implementing an event-driven architecture within the integration landscape facilitates real-time responses and creates a decoupled communication environment between system components, boosting performance. Leverage SAP’s Business Accelerator Hub to enhance efficiency, reduce total cost of ownership (TCO), and minimize development expenses. Adopting an API-led strategy — organizing APIs with centralized governance and policy-based security — to drive reuse and consistency, accelerate delivery, ensure compliance, and enable scalable integrations across the enterprise. Incorporating real-time monitoring tools offers comprehensive visibility into end-to-end processes, enabling quick identification of inefficiencies, minimizing operational risk, improving productivity, and accelerating error resolution.

Empower Excellence And Adaptability Through Operational Excellence

Operational excellence is achieved by developing implementation design guidelines embodying best practices to ensure high-quality standards and comprehensive documentation strategies for transparency and maintainability. Establish a Center of Excellence (CoE) to oversee integration architecture, driving continuous improvement, reducing risk, enforcing standards, and empowering teams through ongoing upskilling and development journeys. This includes regularly updating documentation, maintaining repositories like SAP LeanIX, and fostering hands-on experience through workshops and sandbox environments.

Enable Continuous Innovation Through Regular Optimization

Facilitate continuous innovation by creating an interface repository that provides transparency across the integration landscape, supporting effective decision-making and enhancing governance and security. Regular evaluations and reviews help estimate efforts accurately, prioritize integrations needing modernization, and maintain momentum toward achieving a clean core architecture. These actions ensure sustained growth and competitive advantage through regular optimization and innovation.

Conclusion

Creating a resilient integration strategy requires a comprehensive approach encompassing governance, operation maturity, and continuous enablement. Customers must focus on architecture planning and governance while staying aligned with modern technologies and cloud readiness. This holistic approach not only future-proofs the organization but also ensures alignment with technological advancements as they evolve. A well-defined target integration architecture is crucial as it anticipates the enterprise's landscape over the next 5-10 years, emphasizing the replacement of legacy systems with scalable, agile solutions. Coupled with a robust Integration Governance Framework rooted in clean core principles, businesses can achieve structured adherence to integration strategies using tools like SAP ISA-M for strategic assessment and direction.

The clean core integration principle is a strategic shift from building fragile, custom integrations inside the ERP to a model of using an external, cloud-native platform (SAP BTP) that communicates with the core exclusively through stable, standard interfaces (APIs and Events).
