Story Book 1074: Day 58 - 🚀 #OperationSelfLearning — After-hours build session Today’s milestone: turning a simple idea into a working SAP BTP + CAP + Fiori application. Built hands-on: ☁️ SAP BTP Trial 🛠️ Business Application Studio ⚙️ CAP with Node.js 🧩 CDS domain model — Phases → Topics (1:N) 🔗 OData V4 service 💾 SQLite persistence 🧠 CAP before UPDATE business logic 🖥️ SAP Fiori Elements List Report The real learning was understanding the flow: CDS → CAP → OData → Business Logic → Persistence → Fiori And this small POC is only the foundation. Next: Fiori update → OData PATCH → CAP handler → persistence. Then we evolve the same application: HANA Cloud → APIs → Generative AI Hub → RAG/HANA Vector → MCP → Joule/Agents → Governance 🤖 Small POC. Real implementation. One architecture layer at a time. 💡 #SAP #SAPBTP #SAPCAP #SAPFiori FioriElements NodeJS OData SAPBusinessAI GenerativeAI EnterpriseAI CloudArchitecture LearningByBuilding OperationSelfLearning
