ABAP Doc is an excellent way of integrating documentation into the code.

Eclipse ADT calls it Code element information.

We used to use the APPEND and INSERT commands to add rows to internal tables. Now that ABAP has grown, we can use VALUE, REDUCE, CORRESPONDING, etc. But what if the internal table already has rows and we don’t want to lose them?

A while ago I showed you that you could SELECT from an internal table. And then I asked myself: if that is possible, shouldn’t INNER JOIN be possible too?

Man, this is one of those endless discussions that will never get anywhere. Ditto trying to decide if you deserve to go on living if you put pineapple on your pizza or Philadelphia cheese on your sushi.

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.

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.
