ALV is Application List viewer. Sap provides a set of ALV (ABAP LIST VIEWER) function modules which can be put into use to embellish the output of a report. This set of ALV functions is used to enhance the readability and functionality of any report output.

In such cases, this set of ALV functions can help choose selected columns and arrange the different columns from a report output and also save different variants for report display.
