You need to create code that can be used by multiple programs. Which techniques does SAP recommend?

Using a method in a global class is recommended by SAP for creating code that can be utilized by multiple programs. This approach leverages object-oriented programming principles, offering encapsulation and reusability. When a method is defined in a global class, it can be accessed from various programs, making it easier to maintain and update code in one location rather than in multiple programs.

Global classes are designed specifically for shared functionality and can contain both instance and static methods, providing flexibility depending on how the method needs to be accessed. This capability makes global classes particularly suitable for scenarios where code needs to be reused across different parts of an application or within different applications. Such organization not only promotes consistency but also helps in maintaining clean and manageable code.

While other techniques like using a function module in a function group or creating an include program can offer some benefits, they do not inherently provide the same level of organizational structure and functionality that global classes can. Therefore, utilizing a method in a global class stands out as the best approach when the goal is to create reusable code across multiple programs.
