CD100 News in ABAP - Concepts to Further Increase the Power of ABAP DevelopmentCD100 News in ABAP - Concepts to Further Increase the Power of ABAP DevelopmentTraditionally "ABAP News” gives you an overview of upcoming ABAP language and ABAP Workbench innovations. But this time, don't expect to only hear about new features which are only available in distant releases of the SAP NetWeaver Application Server. We will show you the latest mouthwatering developments in the ABAP programming environment which have been downported and will already be available with in the SAP NetWeaver enhancement package for SAP NetWeaver 7.0. We will cover important technological concepts like secondary keys for internal tables, string templates, boxed components and data streams, locators in Open SQL, and demonstrate how they can be used in your ABAP programs. We will also demonstrate some exciting new features in our ABAP tools, e.g. dominator trees in the memory inspector and the request based and layer aware debugging. Target Audience: Web and Application Development |

CD103 ABAP Development GuidelinesCD103 ABAP Development GuidelinesABAP is a vibrant, evolving language which is almost 30 years old. New developments in ABAP are introduced either through additions to the existing feature set or replacement (and thereby making superfluous or obsolete) of current features while SAP's practice of maintaining strict downward compatibility prevents the total extinction of obsolete features from the language. This issue of superfluity and obsolescence can be troublesome. The ABAP programming guidelines help you to find your way through that jungle of possibilities and to create programs that are correct, robust, readable, maintainable, and up-to-date. Target Audience: Web and Application Development |
