Hi Ahmed,
Good to know you want to get started with SAP.
To let you know SAP has both technical side and functional side. As you have sited your background details, it is more promptly visible that you belong to technical side. Your choices can be very easy to be made with which module you can get started with in SAP.
Below are the following points worth to mention:
1. SAP technical side has ABAP programming which would be of your interest as it is core OOP programming. If you have knowledge in JAVA or C++ it will be good enough to grasp the concepts well.
2. SAP BASIS is more with networking side or say more likely DBA features. It deals with server configuration and maintenance, User creation, maintenance and configuration.
These above two modules that i have listed, its more easy to get started with SAP as a fresher. So be noted: as you dont have any SAP experience, you will be treated as a fresher.
Advantages:
If you get started with SAP and gain experience in it , with all that you have learnt you can abreast other technologies as well with you interest and inclination. From career prospects, there is no stopping anymore as you will constantly grow and keep on leaning.

But people are making their way out and landing into job markets and making it big. So initial hiccups will be there but if you are ready to face and withstand all these challenges , SAP will welcome you with Pomp and Glory.
