Overview of this book

Advanced Business Application Programming (ABAP) is an established and complex programming language in the IT industry. This book is designed to help you use the latest ABAP techniques and apply legacy constructions using practical examples. You'll start with a quick refresher on language and database concepts, followed by agile techniques for adding custom code to a modern ABAP system. After this, you will get up to speed with the complete ABAP toolset for importing data to and from different environments. Next, you'll learn how to print forms and work with the different ABAP tools for Extensible Markup Language (XML) manipulation. While covering further chapters, you'll gain insights into building stunning UI5 interfaces, in addition to learning how to develop simple apps using the Business Object Processing Framework (BOPF). You will also pick up the technique of handling exceptions and performing testing in ABAP. In the concluding chapters, you can look forward to grasping various techniques for optimizing the performance of programs using a variety of performance analysis tools. By the end of this book, you will have the expertise you need to confidently build maintainable programs in Systems, Applications, and Products (SAP).

While the ABAP language itself has built-in mechanisms for creating unit tests, SAP has also equipped us with a powerful extended Computer Aided Test Tool (eCATT) to create complex test scenarios that allow the automation of functional tests.

The availability of this type of tool is very important in a solution that is constantly being developed, and subsequent changes may disturb its stability. Rapid regression tests are the foundation of a modern software development process. In this chapter, we will go through all the important...
