As I have mentioned in my other posts, SAP HCM is a very good option, and there are a lot of opportunities. Having said that, getting a job in the current SAP HCM market could be very difficult, especially for freshers. You seem to have a lot of experience in recruitment. If you are looking to get into SAP, you will need to understand the whole recruitment process, all the phases in recruitment, and how each of them works, not just the functions of a recruiter.
Also, you have to keep in mind that SAP is an ERP (Enterprise Resource Planning software), a huge, complicated software that is ever-expanding. So, you will have to learn a new software and understand client business processes. You will need to configure these processes in SAP as per their requirements. You will be required to know different sub-modules in HR (e.g., Organization Management, Personnel Administration, Performance Management, Compensation Management, e-Recruitment, Payroll, Time Management, etc.).
I am not trying to scare you, but this is the reality. Also, in its latest cloud offering (SuccessFactors), there are recruitment modules like Recruiting Execution, which you could learn. However, you can learn it only through a Partner Company (SAP SuccessFactors partners), and these courses and certifications are very costly. You can find more details on the SAP/SuccessFactors website.
So, as you can see, the path is not that easy. But if you are determined, you could definitely become a consultant (the future is definitely good). So, be ready to give your sweat and blood.
Best of luck. Hope this answers some of your questions.
