Riassunto

· Explore practical exercises for programming in SAP Business Workflow
· Utilize step-by-step instructions for adapting data flows, agent determination, event definitions, and more
· Learn from examples, problem solutions, and tips and tricks for daily practice

ABAP developers require special programming skills for workflow-related ABAP development, as well as very specific process knowledge. With this book, you will acquire both! You’ll learn the aspects of the tools that are directly related to the developer’s tasks, understanding when it is necessary to use custom code and how to write this code. In the many activities and tutorials this book provides, you'll discover how your work differs from the workflow engine of classic application development, as well as how to influence the behavior of a workflow with its own ABAP programs. Additionally, you'll learn how to customize the workflow environment beyond standard programming.
