Hi Satya,
If yoy dont have any experience with any module in SAP then it is better to get trained in some good institute and get certified. Then atleast you will be able to compete in the market. But Remember Certification is not the only parameter you require all you need is a good deep understanding on the basics. As we all know hardwork always pays. Put Your effort and persist on it surely you will get the desired result.
Please go through the below blogs, it will give you better ideas
