What does the term 'modularization' in ABAP refer to?

The term 'modularization' in ABAP refers to organizing code into reusable components. This practice allows developers to break down complex programs into smaller, manageable parts, or modules. By doing so, each module can encapsulate specific functionality that can be reused across different programs or applications, promoting efficiency and maintainability.

Modularization enhances code readability and facilitates easier debugging and testing because logical segments of code are isolated in distinct components. This also aligns with best programming practices, as it reduces redundancy, allowing developers to maintain and update code more efficiently over time.

In contrast, options that mention expanding code for better readability, setting up security checks, or creating a database schema do not capture the essence of modularization, which fundamentally emphasizes code organization and reuse rather than functionality that addresses readability, security, or database design.
