I obsessively package everything that moves.

Did you know that you can finally make radical changes to a development without fear because there is a simple way to undo all those changes?

OO exceptions always need a parent. They always have to inherit from somebody. And ABAP gives them 3 alternatives.

SAP messages are all managed centrally through the SE91 transaction, but can appear to a program in a variety of formats.

I was always told that, when selecting a single record, I should use UP TO 1 ROWS whenever the key was not fully provided. My elementary school teacher told me that I should always aks why: why? Nobody ever told me why.

Let’s say you want to show an url in a SAPScript layout. You place the url in a SAPSCript text and assume everything will work fine. Because most times everything does work fine. It’s just that sometimes…

While writing code, you should always keep present how easy it will be to maintain. This is particularly important in data declarations. And so easy to do right.

In SE24 the class code is partially hidden from the programmer behind a GUI. This is apparently convenient but ultimately limitative.

It took me a long time but I finally got rid of the damn prefixes.

ABAP 7.4 brought a lot of lauded novelties. Of all of them, the one less talked about is MESH. Let’s analyse it and see how unfair that has been.

When you need to make mass changes to ABAP code, the SAPGui IDE isn’t of much help. Eclipse ADT is better, especially if you just want to rename stuff. But there are lots of changes which you won’t be able to automate there. Namely, changes that most be done hundreds of times and which cannot be done with a simple find and replace. In these cases you probably end up changing everything manually. But it doesn’t have to be that way.

When you’re going to modify existing records of a database table it is common to first SELECT them to see how they are and only then UPDATE them with what they will be.

When I get to a new project the system administrator generates a development key for each development system assigned to our SAP username. Usually it’s sent to me by e-mail. Usually I lose track of it.

The new way to get data from internal tables is also the new way to put data into internal tables.
