This handbook on theoretical and practical aspects of the SAP system and the ABAP language can serve as a reference for programmers and SAP users or a review for certification. Beginning with basics then moving on to more advanced topics, the book is suitable for all levels. Material is divided into sections on different programming issues in SAP ABAP, such as the GUI, the ABAP Workbench, internal tables, dialog programming, creating reports, object orientation, and cross-application technologies. Step-by-step instructions are illustrated with b&w screenshots on every page. Implementation-ready program code (requiring mySAP ERP software) is provided to help readers understand various concepts.
