Issues in config of new asset accounting

Hi,

I'm currently setting up the new asset accounting config.

I have activated the relevant Business function and set the new asset accounting to in preparation.

I have changed the deprecation area ledger assignment for most depreciation plans. But there are 1 or 2 which I cannot Change due to the error message ACC_AA116 - "Parallel crcy area (crcy type 31) missing for area 01 ch. of deprec. GB".

I checked everything and compared the depreciation plan and the relevant Company codes to similar dep. plans and Company codes but can't find any difference.

What can I do? Please advise.

Thanks
