Hi Ritesh
From your recruitment background what have your learned about the SAP products other than technology areas? Have you heard much about the SAP HR functional area? If you like recruiting background, etc you might find a pathway using your industry knowledge and experience.
Demand, etc really depends on where you are located. Why not use some of your recruitment experience to search local job portals and see what is sought out for a skill? This may help you understand where the demand in (though it may also tell you where the supply is as well).
