Methods

Quick answer

Understanding a method’s interface, its inputs, output and exceptions, is how you correctly call SAP and custom classes.

Key takeaways

  • A method is a named operation on a class, with parameters (importing/exporting/changing/returning) and possible exceptions…
  • View a class’s methods in SE24/ADT.
  • Read each method’s parameters and exceptions to understand how to call it.
  • Watch out: Guessing instead of using the reference tools.

What it is

A method is a named operation on a class, with parameters (importing/exporting/changing/returning) and possible exceptions (raising). Calling a method invokes that behaviour; RETURNING methods enable clean functional-style calls.

How to find/use it

  • View a class’s methods in SE24/ADT.
  • Read each method’s parameters and exceptions to understand how to call it.
  • Prefer RETURNING for single results; check RAISING for error handling.
  • Look for documented/released methods on public APIs.

Why it matters

Understanding a method’s interface, its inputs, output and exceptions, is how you correctly call SAP and custom classes. Well-designed methods (small, single-purpose, clear parameters) make code readable 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.
