Classes

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.
