Hi Shaan,
Certification part usually comes after learning. let's focus on which module and how it can improve you with your future.
As you are already working in field of IT you have some knowledge / information working in real time scenario and working in companies. Now you have to try to find you key area, which could be are you interested in programming, administrator or some functional activities.
If you really focus on any course you will learn it and will be able to clear those certification some or other way but what's the field of interest ?
If you feel that Administration is strong / positive point what you have then you can have details about SAP Basis, If Programming then ABAP could be good choice.
It will be always good to attend online demos for different modules and try to understand overall picture and then take a decision. While attending demo have all set of questions ready from your end which will help to analysis, Is this what you are looking for ?
I hope I have helped you.
Cheers
Sharma
