SAP® ABAP™ Questions and Answers

Book description

Designed as an introduction to the basics of ABAP or as a quick certification review, this book guides the reader through the intricacies of this programming language used by SAP components and applications (e.g., R/3, NetWeaver, etc.). It is currently positioned, alongside the more recently introduced Java, as the language for programming SAP's Web Application Server, part of its NetWeaver platform for building business applications. The question and answer format provides the reader with all of the details to pass certification exams in a step-by-step, easy to read, method of instruction.
