Practical guides on SAP S/4HANA migration, Clean Core, ABAP, and SAP Business AI (Joule, agents, MCP) — by 15+ year SAP practitioners.https://s4ready.ai/en-ushttps://s4ready.ai/resources/how-sap-joule-works-explained/https://s4ready.ai/resources/how-sap-joule-works-explained/Most SAP professionals know what Joule does. Far fewer can explain how it thinks. Here's the five-step mental model — intent, grounding, reasoning, action — in plain English, and why grounding (not the LLM) is the part that matters for enterprises.Tue, 30 Jun 2026 00:00:00 GMTJouleSAP AIGenerative AILearning Pathhttps://s4ready.ai/resources/how-sap-joule-works-technical-deep-dive/https://s4ready.ai/resources/how-sap-joule-works-technical-deep-dive/Past the chat box, Joule is an orchestration engine: a scenario catalog, a knowledge catalog, RAG-based grounding, data masking, and a skills-and-agents layer that acts on your SAP systems.
