Trending @Wipro; I need your opinion on my career transition.

I have completed almost 2.4years in wipro and i have been working in SAP HCM domain for last 18 Months as my manager didn't give me release stating the project policy of staying 18 months. It was a mistake and another big mistake I made as I didn't learn other things at that time. Now I am trying to switch myself to another domain as SAP HCM is going to be obsoleted. Which will be a good option for me- Success factor or SAP ABAP. So please someone guide me if you know anything about SAP.
