Fixed Assets GL Accounts

Hi,

We have uploaded the fixed assets and after uplaoding the same ran the Asset Balances Report to veiw the details of the acquisition costs and accumulated depreciation in respect of the uploaded assets. The Report is running fine, however, when we view the GL Accounts, using the T Code FAGLL03, the account does not show any balance and the message appears "No items selected". Also when we run the GL Balances Report using the T Code FAGLB03, the message appears "No data found for fiscal year -

". Could any one advise as to why this is happening and what could be the remedy for this ?

Thanks in adavance
