Hi Somasundar,
It seems like a decimal issue in arriving dep % and nothing wrong in any concepts or dep key.
I hope you must be using remaining useful life based depreciation thats why some minor amount difference.
Attach the screenshots of your AFAMA(With Assignment of calc methods of the dep key assigned to the said asset),AFAMS(With Multilevel method assigned in dep key). Let me try to help you further.
Hope it solves.
Regards,
