Introduction:

You must have heard about these fancy terms like new ABAP , advanced ABAP, 7.4 and 7.5X, all these terms are related to the NEW ADVANCED ABAP which is our topic for today.

This blog post will make you familiar with all the above mentioned terms so that you can also help others if they are also wondering why suddenly from the past few years these terms have become a talk of the ABAP town. We will see how it can make an ABAP’s life very easy given the condition that one should get familiar with the new ABAP first.

You must have seen many blog posts on the new ABAP and when I have started my new ABAP journey with the help of these blog posts but one problem which I faced is I was not able to find a single source covering all the topics hence I have to go through many resources , develop code , debug etc to fully understand each concept.

So I thought let’s have all the concepts at one place in a sequential manner covering all the concepts with executable line of code which can help someone who is new to this topic or not able to understand few concepts.
