The ABAP List Viewer (ALV) is a powerful reporting tool in SAP that displays data in a structured grid or table format. It comes with many built-in features such as sorting, filtering, subtotals, totals, column resizing, and even options to export reports to Excel or PDF—all without the need for additional coding. ALV reports are highly user-friendly, enabling business users to analyze and work with data in a way that feels similar to Excel. From a development perspective, ALV can be easily implemented using standard function modules or object-oriented classes like CL_SALV_TABLE, making it both efficient for developers and convenient for end users.
