Keeping up with ABAP

Product Details

In a two-part series on ABAP in the 21st century, Karsten Bohlmann, a development architect from SAP SE, covers recent advancements in the ABAP language. Sigrid Wortmann and Christiane Kettschau from the ABAP Language Team introduce ABAP Managed Database Procedures that allow you to embed native database source code in ABAP applications. Lukas Dietzsch of Blackvard Management Consulting compares Javadoc and ABAP Doc documentation approaches. Rounding out the anthology with tips and best practices for using ABAP are Chris Savelli of COMERIT; Charles (Tim) Soper of SAP; Rehan Zaidi, a senior SAP technical consultant; and George Chen of Lynk, Inc. A bonus article by Dr. Volker Stiehl on SAP HANA Cloud Integration is a sample of another area in which SAP Professional Journal has a significant amount of content.

SAP HANA in-memory technology brings improved performance to standard SAP Business Warehouse (BW) processes. Custom development of ABAP code, however, may require some tweaking to optimize its performance and properly harness the power of SAP HANA. This is especially true for custom ABAP programs that were originally designed to run on older versions of SAP BW based on relational database technology. Learn three ways to execute the analysis of custom ABAP code when migrating an SAP BW application to an SAP HANA database, and how to quickly pinpoint potential issues and find solutions to remediate them.
