Which transaction code is used for managing function modules in the SAP system?

The transaction code SE37 is specifically designed for managing function modules within the SAP system. Function modules are reusable pieces of code that can be invoked from various places in your SAP environment, making them a vital component of SAP development. By using SE37, developers can create, modify, or analyze function modules, which facilitates better organization and reusability of code.

This transaction provides an intuitive interface that allows users to navigate through existing function modules or create new ones. Furthermore, SE37 also allows for the testing of function modules to ensure that they behave as expected before integrating them into larger applications or transactions.

In contrast, the other transaction codes serve different purposes: SE80 is the Object Navigator, which provides a broader view for managing various objects, including function modules, but is not solely focused on them. SE11 is used for data dictionary objects management, such as tables and views, while SE24 is specifically for class management in ABAP Objects. Hence, SE37 is the most appropriate choice for managing function modules directly.
