## Overview

This repository is a hands-on workshop, not an application source tree. Its principal journey is from connecting an ABAP development environment, through Copilot-assisted creation and execution of a travel-and-booking application, to validation and unit testing. The documented runtime centers on an executable class, service, helper, and participant tables; optional branches cover debugging and custom agents. No source excerpts were provided, so runtime relationships below are limited to those explicitly stated in the README.

Main entry points: [`README.md`](https://github.com/mhuber9/abap-platform-rap130/blob/main/README.md) (Travel executable), [`exercises/ex02/README.md`](https://github.com/mhuber9/abap-platform-rap130/blob/main/exercises/ex02/README.md) (App generation), [`exercises/ex03/README.md`](https://github.com/mhuber9/abap-platform-rap130/blob/main/exercises/ex03/README.md) (Sample loading), [`exercises/ex0/README.md`](https://github.com/mhuber9/abap-platform-rap130/blob/main/exercises/ex0/README.md) (Environment setup)
