Hey Arun,
As Arden Stricke has rightly mentioned, you will be considered a fresher for SAP.
Your prior experience will come handy during projects and initial understanding of the systems and the logic behind the processes.
But the growth in SAP field is still better than many other field.
Many people, including me, chose to start as a fresher in SAP only because of the career path it offers.
