Advanced Topics
Everything in this section is something you do to an app that already runs: extend the framework underneath it, connect it to another system, take it to a release or a stack it was not written on, or set up the machine you write it on. None of it is needed for a first app — the Quickstart and the Cookbook come first — and every group below stands on its own.
| Group | What it covers | Start with |
|---|---|---|
| Extensibility | User exits on the HTTP handler, the frontend artifacts as an app of your own, custom UI5 controls | User Exits |
| Integration | Calling abap2UI5 apps on another system over RFC or HTTP, an abap2UI5 app inside a Fiori Elements object page, and AI agents operating apps over MCP — in the system or in a CAP server | RFC Connector |
| Releases, Stacks | The downport to NetWeaver 7.02, renaming the Z2UI5_ prefix, developing in a repository off the stack, converting classic reports for ABAP Cloud, the legacy-free UI5 runtime |
Downporting |
| Developer Setup | The tooling around the framework, the linter, the MCP server, the VS Code extension, and the setup for an AI agent | Tooling |
| Toolchain | The open-source projects the framework is built with — abapGit, ajson, S-RTTI, abaplint, open-abap, abap-cleaner, abapmerge | Toolchain |
