Hi Arun
If you are going to continue down the Finance path - which includes Simple Finance - then perhaps you need to look at some non-vendor specific training in basic Finance concepts (e.g. Accountancy). It sounds from your comments what is holding you back is domain knowledge.
If you like the work you do but need knowledge then consider looking at some MOOCs to joining a course somewhere to learn Finance. From there you will improve your SAP consulting skills (whether you move to Simple Finance or not)
