ABAP TDD in NetWeaver 7.0 EHP2

I showed what the Test-Driven Development cycle might look like in the ABAP Workbench (SE80) in NetWeaver Release 7.01. Unfortunately, the TDD experience in that Release was marred by a hurdle right at the start of the process of implementing an ABAP class. That hurdle has been removed, and there are three other important improvements to ABAP Unit.

With NetWeaver 7.0 EHP2 (Release 7.02), the process has become a little bit more graceful. This weblog reviews what ABAP TDD looks like in practice in Release 7.02.  (Look for even more improvements in support for ABAP TDD in the Customer Engagement: Evaluation of the Pilot Version of ABAP in Eclipse.)

Customer Engagement: Evaluation of the Pilot Version of ABAP in Eclipse

Why ABAP in Eclipse?

The idea of offering an ABAP development environment in Eclipse may surprise some experienced ABAP developers, since the classical ABAP Workbench since years has proved itself as an integrated, comprehensive business development environment with a rich toolset for development, testing, troubleshooting and support running on a powerful server with a sophisticated, robust life cycle management. On the other hand Eclipse has established itself in the world as a state-of-the-art open development platform with the powerful UI capabilities, which are second to none and nowadays many developers are fascinated by its usability, productivity and flexibility.

What program type?

This is a question I have often reflected on. When I create an OO based dialogue application, what kind of program should I use? Since the program has to manage at least one dynpro, we could choose between three types of program for our application:

• A module pool
• A function group
• A report

News in ABAP Debugger Breakpoints and Watchpoints ,Statement Debugging

SAP NetWeaver 7.0 EHP2 brings an expanded set of breakpoint and watchpoint capabilities as well as a new higher-resolution statement debugging capability (of course in the New ABAP Debugger!).

This blog shows how to use these new features:

• The new types of breakpoint (on ABAP command, on Web Dynpro entities, on method of a class, on Simple Transformations…)
• The new types of watchpoints (on internal table, on ABAP objects and object attributes…)
• The new conditional breakpoints and watchpoints

Displaying Internal Tables in the Debugger in NetWeaver 7.0 EHP2

The New ABAP Debugger, introduced with NetWeaver 2004s, came with a Table tool for displaying the contents of internal tables.

With NetWeaver 7.0 EHP2 and with Netweaver 7.30, the Table tool has been re-worked and expanded to make it easier to use and more flexible – a truly comfortable tool for examining internal tables, no matter how large or complex they might be.

A second way to get the new ABAP editor in LSMW

In my previous blog ‘How to get the new ABAP editor in LSMW’ I described how a single enhancement enables the new ABAP editor in SAP’s LSMW. While that solution only takes one implicit enhancement spot, it has a few (minor) limitations. In this next blog I will describe another approach to enabling the new ABAP editor in LSMW. This new solution is slightly more invasive, but gives us much more flexibility.

How to get the new ABAP editor in LSMW

SAP LSM Workbench (LSMW) has for years been a much used tool for data migration into SAP. It is both loved and hated  While LSMW has had its last update in 2004 it remains a much used tool in this age of more modern toolsets such as SLT,  SAP DS and the like.

For many frequent and hard core users of LSMW a big nuisance is the old style ABAP editor. This old editor takes up alot of development time, especially in those ABAP-rich LSMW projects.

One night, bored and out of beer, I managed to develop a relatively simple enhancement that enables the new ABAP editor for LSMW.

SAP AS ABAP – Authentication using X.509 Client Certificates

This document shows how to configure SAP AS ABAP for authentication with x.509 client certificates. It shows the procedure used to create a simple Certification Authority (CA) using OpenSSL and how to generate client certificates from this CA.

Enabling SSL

Install the SAP Cryptographic Library. The following are minimal parameters to enable SSL

• ssl\ssl_lib = S:\usr\sap\K20\SYS\exe\run\sapcrypto.dll
• sec\libsapsecu = S:\usr\sap\K20\SYS\exe\run\sapcrypto.dll
• sec\ssfapi_lib = S:\usr\sap\K20\SYS\exe\run\sapcrypto.dll
• ssf\name = SAPSECULIB
• icm\server_port_1 = PROT=HTTPS, PROT=1443, TIMEOUT=900
• icm/HTTPS/verify_client = 1
