Writing Sap Abap/4 Programs

The Best Available Guide to Mastering Sap ABAP/4 Programming Language! The massive amount of information and integration inherent to SAP makes it unique, but also makes programming within ABAP/4 a challenge. Now, for the first time, a world-class SAP coder reveals his own "reality-tested" solutions to typical programming tasks. More than a mere rehash of SAP's on-line and/or printed documentation, the author explores topics and techniques that are simply not covered, or not as clearly covered, elsewhere. From writing basic reports to performing SAP updates, dozens of examples show you just how to do it - or how to do it better! Key topics include: A detailed framework for creating an ABAP/4 program; Data retrieval and display; Developing an interface for data from legacy systems; Providing user interaction with displayed data; External data acess; Using the SAP debug facility. Perhaps most useful of all are the original shell programming routines, developed by the author to standardize and simplify coding. The accompanying CD-ROM contains all of the SAP code referenced in the text, along with detailed techniques for coding and specific explanations of the methods used.
