Hi Yuvraj,
You have not mentioned about no of years of your domain experiance. For SAP functional consultant they will ask for minimum three years of domain experiance (other than SAP experience).....
Based on your domain experience it would be better if you choose Production Planning module for getting in to SAP.....
Learn SAP PP from a good institute and then start for job searching....Practice a lot on the IDES system... Initially it will take some time to get in to SAP career...have patience...Lot of hard work required to excel as a SAP functional consultant....
All the best...
Thanks
Kumar
