It encompasses disciplined business processes aligned to SAP best practices, upgrade\u2011stable and observable integrations, trusted data that delivers real\u2011time business insight, and efficient operations that remain current and resilient. Together, these dimensions establish the governance, architectural integrity, and future readiness required to support AI adoption, cloud modernization, and sustained digital transformation.<\/p>\n<p>Adherence to Clean Core ensures SAP S\/4HANA remains stable, upgrade\u2011ready, and innovation\u2011friendly. By minimizing custom code and adopting SAP\u2011approved extensibility patterns, organizations create an ERP landscape that is both future\u2011proof and cloud-ready.<\/p>\n<p>SAP\u2019s modern extensibility model provides a clear decision framework &#8211; classifying extensions as:<\/p>\n<ul>\n<li>(A) Cloud\u2011ready public APIs<\/li>\n<li>(B) Stable classic APIs<\/li>\n<li>(C) Conditionally allowed internal objects<\/li>\n<li>(D) Explicitly non\u2011compliant approaches such as direct table writes<\/li>\n<\/ul>\n<p>This guidance enables organizations to prioritize remediation, address the highest\u2011risk patterns first, and adopt Clean Core in a structured, achievable way. Clean Core is a continuous journey, requiring organizations to assess their current state, define a target Clean Core posture, and execute against a time\u2011bound roadmap aligned to business priorities.<\/p>\n<p>Infosys\u2019 <strong>6R<\/strong> methodology provides a structured journey: <strong>Reset, Retire, Replace, Realign, Refactor, and Retain<\/strong>, which is supported by the Decoupling Analyzer.
