Purpose
The purpose of this tutorial is to provide an easy and quick reference that may be used as a guide while coding to build lists using ALV Grid Control. Actually, there is easy-to-reach information about implementing ALV Grid lists. However, it is generally required to find the information sought in a quicker way. This tutorial handles this, being a condensed source that can be used as a “guide.” It will not deal with the technical infrastructure on which ALV lays. Some of the tables are taken from the online SAP Library, which is the most trustable source about the topic. Shortly, this will be a booklet summarizing major capabilities of the ALV Grid Control.
To get deep into the ALV Grid control, you can refer to the standard SAP course “BC412 – ABAP Dialog Programming Using EnjoySAP Controls” and the book “Controls Technology”. Also you had better inspect demo programs.
