error while posting asset aquisition

Hi to All,

I am getting following error while posting aquisition entry.

"Company code 211 manages parallel currencies in Asset Accounting. For each area that posts automatically online to FI, you have to define one dependent depreciation area that adopts both identical values and depreciation terms from depreciation area 01, and which is assigned to currency type 30 and currency GBP. There is no depreciation area of this type defined for depreciation area 01"

I had made all settings what the error says above but still error persists.

PLEASE ITS VERY URGENT
