What is the function of the ALV (ABAP List Viewer) in SAP?

The ALV (ABAP List Viewer) serves a pivotal role in SAP by facilitating the display of data in a structured and organized format. It provides developers and users with a powerful tool to present data in a tabular form, enhancing readability and usability. The ALV enables sorting, filtering, and formatting of data, which significantly improves the user experience when dealing with large datasets.

By using ALV, developers can create various report outputs with minimal coding effort, while still allowing end users to interact with the data through features like dynamic column adjustment and export options, such as sending data to Excel. This structured presentation of data empowers users to analyze and interpret the information effectively, making it a vital component for reporting within the SAP environment.

In contrast, the other options pertain to functionalities that do not align with the primary role of ALV. Creating layouts for system settings, managing user authorizations, and handling database transactions are distinct functions that require different tools and processes within the SAP landscape.
