AI-Powered SAP Extensions: Clean Core Strategies

SAP Clean Core Mar 3, 2024


SAP is an ecosystem that provides intelligent solutions for businesses that are flexible and scalable. However, no one-size-fits-all solution can cater to the needs of all organizations worldwide, as each company operates in a unique way. Therefore, it is necessary to customize or build a solution that specifically addresses the particular pain points of each business. 

Understanding side-by-side extension: 

Developers face a new challenge when creating large ABAP programs on public cloud systems. Unlike on-premise systems, creating such extensions directly on the cloud system is impossible as it is a shared system. Although in-app extensions within the system can fulfill individual requirements to some extent, they are not enough for companies needing a more extensive SAP S/4HANA Cloud system extension. In this case, companies can opt for a side-by-side extension, developed using various tools and services of the SAP Business Technology Platform (SAP BTP).  

These side-by-side extensions offer more flexibility than in-app extensions and keep the SAP Core clean. This brings us to this new term, SAP Clean Core. 

Why SAP Clean Core? 

SAP Clean Core is a term used to describe an approach and a concept aimed at achieving a modern, flexible, and cloud-compliant SAP S/4HANA Cloud system. This approach involves integrating and extending SAP S/4HANA Cloud to ensure optimal master data quality and proper business process governance. By adopting this approach, customers can experience better maintainability and lower total cost of ownership (TCO) for their SAP S/4HANA Cloud system. 

Clean Core Extensibility 

On the other hand, Clean Core Extensibility is an extension methodology that ensures that any extensions are kept separate from the SAP application. Extensions only access SAP business objects through well-defined and upgrade-stable interfaces. 

Traditional ERP:  

The following characteristics define an ineffective traditional ERP,

  • Technical debt: Traditional SAP ERP systems can lead to significant technical debt due to heavy customizations tailored to specific business needs. Customizations can cause business disruptions and prolong upgrade cycles as they often need reworking to fit new updates or versions. 
  • Data issues: High data volumes can become unwieldy, leading to data management difficulties and quality issues. Data accuracy, consistency, and completeness are crucial for informed decision-making but are often compromised in traditional systems. 
  • Ineffective business process: Outdated ERP systems may no longer align with current business processes, leading to inefficiencies. There might be a lack of clarity in the transformation path for businesses, hindering effective evolution and adaptation to market changes. 
  • Complex integrations: Integrating traditional ERPs with other modern systems can be complex due to problems with conventional APIs. Managing these integrations can be challenging, requiring substantial IT resources and expertise. 
  • Lack of discipline in operations: Traditional ERP systems may not support the agile operations needed in today’s fast-paced business environments. Stressful SAP releases can occur if the ERP system is not managed with disciplined operations, leading to errors and downtime. 
  • Unreliable software stack: Outdated or unstable software versions can lead to a lack of reliability in the ERP system. This can cause system outages or errors, impacting business continuity and performance.
