Classes
Classes are the object-oriented building blocks of modern ABAP, delivered by SAP and created by developers, encapsulating data and methods. This reference explains global classes and how to explore them.
Quick answer
Modern ABAP is object-oriented, so classes are central.
Key takeaways
- A global class (in the class library) bundles attributes and methods behind a defined interface, reusable across the system.
- Use SE24 (Class Builder) or ADT to view a class.
- Explore its public methods and their parameters.
- Watch out: Guessing instead of using the reference tools.
What it is
A global class (in the class library) bundles attributes and methods behind a defined interface, reusable across the system. SAP delivers many utility and API classes (e.g. CL_SALV_TABLE for ALV, CL_GUI_* for UI); RAP and modern APIs are class-based.
How to find/use it
- Use
SE24(Class Builder) or ADT to view a class. - Explore its public methods and their parameters.
- Prefer released/documented classes for stable use.
- Reuse SAP utility classes rather than reinventing logic.
Why it matters
Modern ABAP is object-oriented, so classes are central. Knowing the key SAP-delivered classes (and how to read a class’s interface) speeds development and keeps code clean and reusable.
Common pitfalls
- Guessing instead of using the reference tools.
- Editing/using without understanding the object.
- Relying on memory for details you can look up.
