i can help you in giving an idea of how you can get to know about which country has more requirement for SAP Consultants.
Please go to the partners list in www.sap.com and filter it country wise/continent wise. you can get the approximate understanding, because if there are more SAP partners available in a region then that means that the demand for SAP consultants is more there.
an SAP Education Consultant
I agree with Julius, always gve a background of your own and which module are you asking about?
Very very subjective answers to this question.. but I would say that the SAP Job market is growing in India (though the pay is never good) and Singapore also has a lot of opportunities.
But it all depends on what level yu are, where have you worked earlier and what are your skills / module specialisation.
Anyways, all the best with your career !
