Fisrt your asset has no value, so you can not retire that asset. If you want to deactivate the asset without values yiu can mark it for deletion or update the deactivation date manually in asset master data AS02.
The asset has no depreciation area maintained as per your error in AW01n, that means your asset has no depreciation area. The asset was created when the depreciation areas were deactivated on transaction code OAYZ.
Thanks!
