Clean ABAP

Developers who write ABAP and want their code tidier will find this guide useful. It accompanies the Clean ABAP repository on GitHub and gathers recommended practices from experienced members of the ABAP community, aimed at producing effective code. The opening chapters explain what clean ABAP means, why it matters, and when to apply each practice, including how to handle legacy code and performance concerns.

The core of the book covers the reasoning and method behind each practice. Readers learn how to structure classes and interfaces, design methods and control flow, choose meaningful names, manage variables and literals, work with internal tables, and write helpful comments with consistent formatting. Error handling, designing and running unit tests, and organizing code into packages are also covered, so the book works as a complete style guide that extends from writing code to troubleshooting and testing.

Each practice is illustrated with detailed examples that contrast clean code with messy code, making the differences easy to see. Together these examples help readers write code that is more readable and maintainable.
