Hi Manas,
I can understand your situation. May I know from which institute you have done your SAP SD course? Was it from Atos or unauthorized institute?
If its from Auto's you will get some opportunities, but, you have to wait for a while. Frankly, the current market in India is not so bright. Even experienced people are having hard time to get the good break. Sincere suggestion, don't resign the current job.. continue to work and keep searching for SAP jobs.
Practice as much as possible in IDES, try to participate in SCN - SAP SD spaces.Understand the problems faced by others and resolutions given by the members.
All the best.
Regards, Sai Krishna.
