Managing complex custom code in your SAP system can impede your team's efficiency, productivity, and ability to innovate due to the technical debt accumulating over time. Fortunately, SAP's Clean Core approach offers a solution. Clean Core is an approach to implementing and managing enterprise resource planning (ERP) systems, particularly SAP S/4HANA, to minimize customizations to the core system and encourage using pre-built extensions or low-code development tools for additional functionalities. Think of it as streamlining your operations, keeping the essential systems at their peak while building additional functionalities and innovations with Mendix and SAP.

Clean Core isn't about cutting off features—it's about realizing your full potential. By streamlining your core and building outwards, with the support of expert SAP consulting services, you'll increase agility, boost efficiency, and drive innovation, ultimately bringing greater value to your business.

SAP Clean Core approach

Enterprise resource planning (ERP) systems must be streamlined to keep up with competition, and a Clean Core strategy can help. Clean Core creates a more manageable and adaptable ERP system, decoupling core functionalities from custom extensions. This strategy decreases complexity, minimizes customizations, and facilitates smooth upgrades. 

Clean Core aims to attain a contemporary, adaptable, and cloud-compatible SAP  implementation. The Clean Core solution for SAP S/4HANA reduces the total cost of ownership (TCO) while providing better maintainability and flexibility.

The top challenges facing current ERP systems, as identified by IDC's SaaSPath Survey, are related to cost and complexity. The survey found that 23% of respondents consider the cost of implementation to be the biggest hurdle, followed closely by the cost of maintenance and upgrades/customizations (both at 22%). These financial concerns highlight the need for more affordable and adaptable ERP solutions. Additionally, 16% of respondents struggle with the ease of system implementation, and 14% find ongoing performance optimization difficult, indicating that user-friendliness and system efficiency are key areas for improvement.

The most challenging aspects of current ERP systems

With the help of SAP Clean Core, you will be able to address these and other challenges, as well as reap significant benefits. Let’s take a more detailed look at them.
