Agentic UI Extensibility: The Next Chapter of SAPUI5 Flexibility

A Devtoberfest 2026 session on SAPUI5 flexibility: a recap of key-user adaptationKey-user adaptationcapabilityChanging a delivered app without modifying it — moving, hiding and adding elements as a layered set of changes that survive an upgrade.SAP only as deltas that survive an upgrade, then a lab preview in which Joule works through a pasted list of adaptation requests inside the key-user tooling — moving a section, adding one through embedded content, saving and activating a version — and writes a handover prompt when a request is outside what a key user may change. The developer half pastes that prompt into VS Code, where a coding agent generates an adaptation project through MCP tools, picks up the key-user changes already made, reads the base application's metadata and the UI5 documentation, writes the XML fragments and controller extensions for a new table column and a supplier dialogue, and restarts the editor to verify both appear. The agentic parts are unreleased; what the session shows as already available is the adaptation project for Cloud Foundry in VS Code, role-specific adaptation on Cloud Foundry from SAPUI5 1.146, views in variant management loaded when the manage-views dialogue opens rather than at startup, and the redesigned key-user adaptation mode with its change highlighting and version dialogue.
