First question: Do you enjoy programming?
IF <you enjoy programming>.
perhaps a career in SAP ABAP programming is a good idea
find something else.
A bit of humor there. Sorry.
Please check out SAP Career Blog Links. In particular the Advice for freshers blog and the Learning SAP series. If your goal is to get started in SAP and you have no preference at all for what you do (an extremely bad idea, by the way), then yes ABAP programmers and SAP Basis folks have the best chance of being hired without previous work experience (because companies see your programming coursework as being sufficient for entry level jobs).
On the other hand, this is your career. You're going to spend the greater part of your working hours doing whatever it is you get hired to do. It might be a good idea to make sure that you actually enjoy whatever it is you're getting paid to do. Pursuing a paycheck, simply for the sake of a paycheck, is a recipe for disaster and early career burnout.
Hope this helps!
