ABAP Programming - An Integrated Overview

With Release 4.0 and the debut of ABAP Objects, SAP is replacing the classical distinction between reporting and transaction programming with an integrated view, recognizing the simple fact that all application logic is programmed in ABAP and that the application can communicate with the user via screens and with the database via a common interface. Changing between programming types (i.e., doing reporting during a transaction) is a simple and natural part of the language — one that should be exploited if you want to use ABAP efficiently. This article provides new ABAP programmers with a fresh, integrated overview of the language, and experienced ABAP programmers, who may be used to reporting or dialog programming, with the necessary insights to overcome the gap between these classical programming types and ultimately better prepare you to work with ABAP Objects.
