Introduction

The SAP List Viewer is a generic tool that outputs data in a table form (rows and columns), with integrated functions to manipulate output (sort, totals, filter, column order, hide, etc.) and export it (Excel, Crystal report, CSV files, etc.) It is also possible to make ALV editable via ALV control.

ALV name comes from "ABAP List Viewer", as named initially because it was only available in ABAP. It is now a more general concept, which is available in java too (since 7.1).

ALV tool proposes 3 display types (schemes are taken from the SAP Library - An Overview of ALV Tools) and in several technologies:

  • Display types:
    • Simple list:
    • Hierarchical sequential list:
    • Tree
  • Technologies:
    • List
    • Control Framework
      In SAP release 4.5b was introduced the Control Framework. A control was made available for ALVs, known as ALV grid. It can be used in 3 ways:
      • Direct use of control
      • Function module wrapper. It may be used in full screen mode, which means that the buttons are displayed in the application toolbar, and also in popup mode.
      • Object-oriented wrapper, since basis 6.40. Full screen and popup are also available.
    • Web Dynpro
      • Web Dynpro for ABAP
      • Web Dynpro for java (since NetWeaver 7.10)
