Fiori Elements
Fiori Elements is SAP's metadata-driven UI framework that renders standard SAP Fiori floorplans (List Report, Object Page, Overview Page, Worklist) directly from OData V4 services and CDS/RAP annotations, eliminating custom UI5 coding for most transactional and analytical apps. This topic covers the architectural rationale, annotation-driven design, runtime rendering flow, extension points, and production troubleshooting for Fiori Elements apps built on RAP-based business objects.

Lessons in this topic
- Designing List Report and Object Page Apps with UI AnnotationsLearn how to configure List Report and Object Page floorplans in detail using @UI annotations, headers, facets, tables, and actions wired to RAP behavior, including runtime binding to OData V4.
- Extending Fiori Elements Apps with the Flexible Programming ModelLearn how to add custom logic, actions, and UI fragments to a generated Fiori Elements app without breaking the annotation-driven contract, using the flexible programming model's controller extensions and extension points.
- Architecting Enterprise-Scale Fiori Elements Apps: Performance, Draft Complexity, and Clean Core GovernanceDesign decisions for large, multi-entity Fiori Elements applications covering deep navigation performance, complex draft hierarchies, custom extension governance, and clean-core-compliant lifecycle management across landscapes.
- Why Fiori Elements Exists and How It Renders UIs from MetadataUnderstand the business and technical purpose of Fiori Elements, how it differs from freestyle SAPUI5 development, and how CDS annotations drive UI rendering at runtime.
