What is the primary function of the SAP ABAP Dictionary?

The SAP ABAP Dictionary is primarily responsible for defining and managing database objects. This includes the creation and maintenance of tables, views, data elements, domains, and various other database structures. The ABAP Dictionary forms the backbone of data management within the SAP system, ensuring data integrity and consistency.

By using the ABAP Dictionary, developers can define how data is stored, what types of data can be stored, and how different data structures are related to each other. This is critical for creating a robust and well-structured database that supports effective application development in SAP. The dictionary also allows for data definition adjustments without impacting application logic directly, promoting modular and maintainable code development.

The other options reflect different functionalities within the SAP ecosystem but do not pertain specifically to the objectives of the ABAP Dictionary. For instance, managing user interfaces relates to UI5 or other front-end technologies, report generation is handled through tools like SAP Smart Forms or SAPscript, and security roles are managed via the appropriate authorization management tools in SAP.
