Prashant,
Your experience in SAP is of interest since there is a lack of SAP Consultants in this country. However, SAP Consultants usually have had experience in full cycle implementations. In your case, the FI and CO modules. I do believe that your chances will be better if you remain on the I.T side. I would continue to study and ,possibly, obtain a Bachelors Degree in Computer Science. I am not sure what type of Diploma you have but normally a Bachelors Degree is an organizations benchmark for getting in.
I hope this helps,
Harry
