What the heck is a quine, you might ask? Wikipedia says: A quine is a computer program which takes no input and produces a copy of its own source code as its only output. The standard terms for these programs in the computability theory and computer science literature are “self-replicating programs”, “self-reproducing programs”, and “self-copying programs”. If you have watched the Art Of Code talk by Dylan Beattie, you might remember the section about Quines. If not, I highly recommend to watch it. It’s very…

Design patterns are one of the most important things in programming. At a certain point in your own programming career you will have to deal with design patterns. And still some programmers have no idea, what design patterns are and what they are for. If you are a programmer and you don’t know anything about design patterns, then it’s time to learn.

Probably everyone has encountered this at some point. The value in the target field has been truncated by an assignment or an undesired rounding has occurred. The lossless operator EXACT can be used to check lossless assignments or lossless calculations. If lossless transfer is not possible, an exception is raised.   Example 1 – Lossless assignment   Here is a very simple example. The program checks if there is a data loss when assigning a…

ABAP CDS View Entities are the backbone of the new ABAP RESTful Application Programming Model (ABAP RAP). But ABAP CDS is not only used to define the data model – it also has a built-in Access Control to restrict the returned data. These CDS Roles are defined with the Data Control Language (DCL) and can be thought of as an additional where clause.   CDS View Entity Material Plant @AccessControl.authorizationCheck: #CHECK @EndUserText.label: ‘Material Plant’ define…

In Austria there is a famous song by Wolfgang Ambros which goes like this “Skiiiiiiifoan, Skiiiiiifoan, Skifoan ist das leiwandste, was ma si nur vorstö’n kann”  (“skiing is the greatest thing you can think of”). That’s true, skiing is a really great hobby and sport, but well, the environmental impact is quite bad. But there’s something which is nearly as bad: the source code of this ancient piece of software that you have to take…
