About
The SAP Clean Core mind map template provides a structured breakdown of the architectural strategy for separating custom code from standard SAP code to enable smoother upgrades and cloud transitions. Created by Warren Eiserman in September 2023, this 63-node template covers key concepts, the 3R strategy (Retire, Refactor, Rebuild), SAP-provided extensibility options, and curated links to resources. It includes specific nodes like 'SAP Custom Code Analyser' and 'Side-by-side extensibility with BTP', making it a practical cheat sheet for CIOs and SAP architects planning S/4HANA migrations. The template is organized into five main branches: What?, Why?, How?, Links & Articles, and 3rd Party Accelerators, offering a comprehensive overview of clean core principles.
