Web Dynpro ABAP, a NetWeaver web application user interface tool from SAP, enables web programming connected to SAP systems. The authors' main focus was to create a book based on their own practical experience. Each chapter includes examples that guide the reader through the content step-by-step, allowing them to gradually explore and understand the Web Dynpro ABAP process. The authors specifically explain how to design Web Dynpro components, data binding, interface methods, and view controller methods. They also describe other SAP NetWeaver elements, such as ABAP Dictionary and Authorization, as well as the integration of the Web Dynpro application into the SAP NetWeaver Portal. The new edition has been expanded to include chapters on topics such as power lists, creating modal windows and external windows, and using Web Dynpro application parameters and shared objects for communication.
