published by Volker Wegert on 11. December 2014 - 0:00

I've written and published three books on i.s.h.med Parametrierbare Medizinische Dokumentation (PMD) that are now available - for now, there's only a German edition. You can buy the books at your preferred online or local bookstore, but you can also order them directly from me - check the website www.pmd-buch.de for more information.

This is a repost of an article published on the SAP Community Network.

Welcome back to another ABAP Trapdoors article. It’s been a while – I’ve posted my last article in 2011. In the meantime, I’ve collected a number of interesting topics. If you’re interested in the older articles, you can find the links at the end of this article.

ABAP Trapdoors: Death By STRING

As in the previous post, this one is a trapdoor to be avoided by framework and toolkit designers rather than their users.

ABAP Trapdoors: Type Lock-In

This is a repost of an article published on the SAP Community Network.

In the past ABAP Trapdoor blogs, I've written about various problems that can occur when actually writing code in ABAP. Today's issue is more about a structural or design problem. For this example, we'll use the following class hierarchy:

ABAP Trapdoors: LOOP Dizziness

First off, I'd like to apologize for the delay since my last ABAP trapdoor article. I'm really grateful for all of the kind responses I'm getting for these articles. However, having a 14-months-old toddler around invariably implies having all kind of germs around, and some of them apparently teamed up to knock me out for some time...

ALV Grid Function Code Reference

published by Volker Wegert on 20. February 2011 - 0:00

Once again, I had to deal with the ALV Grid and its default toolbar. Since I'm notoriously bad when it comes to remembering the function code constants that are used to disable the toolbar buttons, I've thrown together a small reference card. Perhaps someone else might be interested in this too...

MDD meets ABAP

published by Volker Wegert on 12. October 2009 - 0:00

MDD is a hot topic for some time now. With the arrival of powerful tools like EMF an oAW, it's become possible to actually use the benefits of model-driven development without spending too much time and money on the tools. MDD has long reached it's break-even point between intellectual investment and development speed-up for certain types of projects. It's not the solution to all problems, but it's a really powerful technique with a set of stable and proven tools available.
