For doing any such course, check if you can do it from Centrally Recognised Universities. Many international companies do not have any license in their own country, but they set up their offices in India to make money. Even people run after them as others are doing.
DOEACC Society for IT Courses
How many of us know about the DOEACC society, which provides courses on IT? According to me, for any IT course, DOEACC is the best institute in India, better than any other private educational institute. I am not sure if they offer SAP courses.
Don't waste money with private organizations that are not affiliated in their own country.
SAP Courses in India
For SAP, SAP dealers are available in India. Check their websites. It's better to call their head office and inquire about such courses. They will at least guide you in this matter. It's better to have information than to put your money just for the sake of a course.
