"ABAP Development Essentials" "ABAP Development Essentials" is a comprehensive guidebook designed for today’s enterprise ABAP developer, architect, or technical lead. Spanning foundational architecture through to next-generation modernization, this reference masterfully navigates the full spectrum of ABAP development in SAP environments. Readers begin with an in-depth exploration of the ABAP platform’s architecture, security frameworks, and continuous integration strategies—laying a solid groundwork for understanding the ecosystem’s complexities and critical delivery pipelines. As the chapters progress, the book delves into modern and advanced ABAP language constructs, covering everything from procedural and object-oriented paradigms to dynamic programming, performance-aware techniques, and innovative database integration options such as Core Data Services and ABAP Managed Database Procedures. It provides practical guidance for building high-quality, scalable applications on classic and modern user interface technologies—from SAP GUI and Web Dynpro, to Fiori Elements and the ABAP RESTful Application Programming Model. Seamlessly integrating real-world best practices, it equips readers to interface with SAP and non-SAP systems using RFC, OData, event-driven architectures, and cloud-based services. The journey continues through robust strategies for testing, security, and compliance—ensuring not only reliable performance but also regulatory adherence and data protection in mission-critical environments. Final chapters offer forward-looking insights on legacy system modernization, cloud-readiness, and the integration of artificial intelligence into ABAP landscapes. With expert advice on architectural patterns, DevOps, open-source collaboration, and continuous delivery, "ABAP Development Essentials" stands as an authoritative reference for professionals seeking to master enterprise-grade ABAP development for today and tomorrow.
ABAP Development for SAP NetWeaver BI - User Exits and BAdIs
User exits and Business Add-Ins (BAdIs) provide ideal approaches to extend and optimise your standard SAP system with custom developments. This book teaches you to implement these adaptations in ABAP for use in SAP NetWeaver BI. The book is written for BI consultants who have basic knowledge of ABAP as well as ABAP programmers who want to get started with BI development. After a brief overview of high-performance ABAP programming, you’ll learn how to structure the data flow from the source system up to the report and planning level using practical workshops. Readers learn how to use all of the capabilities of SAP NetWeaver BI, from transformation, including the derivation of characteristics and key figures, to start and end routines and transfer and update rules and benefit from expert instruction and techniques to implement even the most complex requirements with a limited amount of work, simply knowing how to choose the right user exits. An entirely new chapter in this edition describes how you can enhance the SAP BW-BPS planning components and the BI-Integrated Planning tool. Although this book is based on SAP NetWeaver BI 7.0, it also outlines the essential differences from previous releases as needed. With volumes of commented code examples, this book enables you to quickly and easily implement your own custom developments, step-by-step, in your daily work.
