ABAP Development for SAP BW - User Exits and BAdIs

Más información sobre el libro

Readers quickly learn the basics and dive into all key aspects of high-performance ABAP programming techniques, plus uncover the options available to manipulate the data flow from the source system through to the report. In addition, you learn how to develop extractor exits and their extensions, and how best to customize data in SAP NetWeaver BI -- from transformation including the derivation of characteristics and key figures -- to start and end routines to transfer and update rules. You can implement your own custom developments, step-by-step, using the final chapter on variable exits and the corresponding, extensively commented code samples. Although this SAP Press Essentials guide is based on SAP NetWeaver BI (SAP NetWeaver 2004s Release) it also discusses previous releases by outlining the key differences wherever necessary. The book is ideally suited for developers supporting a release upgrade, but it also serves as a highly useful reference book.
