Hardcover. Condizione: gut. Auflage: 1 (September 2004). With a strong focus on the RFC Library, this book gives beginners a first-hand introduction to basic concepts, and highlights key tools in the ABAP Workbench. Actual programming examples help to illustrate client-server architecture, and show you how to assess the appropriate tools for error diagnosis, troubleshooting and more. Experienced SAP developers can dive right into comprehensive chapters on programming the RFC interface, and advanced techniques such as tRFC, qRFC, and parallel processing. Extensive coverage of BAPIs, ActiveX, JCo and highly-detailed programming examples serve to round out this exceptional resource. Highlights include- ABAP Workbench tools - Developing client/server applications - In-depth guidance on the RFC Library - tRFC, qRFC, and parallel processing - RFC Troubleshooting - Business Objects, BAPIs, and ActiveX - Java Connector (JCo) Synopsis Deals with computers/software. 1-59229-034-5 / 1592290345 ISBN-13 978-1-59229-034-5 / 9781592290345 Introduction 1.
