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.

Function Module Description
REUSE_ALV_LIST_DISPLAY Display an ALV list
REUSE_ALV_GRID_DISPLAY Display an ALV grid
