As government agencies transition from legacy SAP ERP systems to SAP S/4HANA, outdated and overly customized code presents a major barrier to successful upgrades. This white paper outlines a strategy for achieving a clean SAP S/4 implementation by eliminating in-core customizations and using Mendix (a low-code/no-code development platform) for necessary extensions. By decoupling non-standard functionality from the SAP core and rebuilding it in Mendix, organizations can reduce technical debt, streamline upgrades, and maintain system flexibility.
This article highlights how Mendix enables rapid application development, even for teams with limited SAP-specific skills, and supports integration with SAP and other systems through certified connectors and APIs. This clean core strategy not only lowers operational costs and enhances security compliance (including FedRAMP support), but also accelerates time-to-value for new features. Ultimately, this approach empowers agencies to modernize their ERP infrastructure with future-proof, scalable solutions that support continuous innovation across cloud and on-premises environments.
