Depreciation calculated wrongly

Hi,

While I am checking depreciation for asset which I acquired on 14.10.2014 and my cut off date is 31.10.2014, the system is calculating depreciation for 31 days in November. I have checked settings in AFAMA and OAYZ and also checked the period controls. Correct fiscal year variant has been assigned to company code.

Kindly help.

Thanks

Rohit
