Hi,
I am afraid this is not possible. Please see the SAP notes
- 152888 - Different fiscal year variants in FI-AA
- 1493253 - Different fiscal year variants in FI-AA (II)
There are a restrictions for different fiscal year variants in asset accounting. This also applies to NewGL. There is a workaround with another depreciation area but I have never tried it.
Kind Regards,
Steffen
