What is SAP ALV?
ALV stands for ABAP List Viewer. ALV gives us a standard List format and user interface to all our ABAP reports. ALV is created by a set of standard function modules provided by SAP.
ALV provides a lot of inbuilt functions to our reports and some of the functions are listed below.
Sorting of records
Filtering of records
Totals and Sub-totals
Download the report output to Excel/HTML
Changing the order of the columns in the report
Hide the unwanted columns from the report
Because of the above functions, ALV substantially decreases the report development time. ALV takes care of rendering the list and we can concentrate only on the data retrieval part.
Some of the function modules used to create ALV reports are listed below.
