Change of Time Dependent data in Asset Master

When I am trying to change the Cost center in the Asset Master, I am getting the following error:

Fiscal year 2007 is already closed in Financial Accounting.

Message no. AA669

Diagnosis

You have initiated a recalculation of asset values for fiscal year 2007. However, fiscal year 2007 is still open is Asset Accounting, but not in Financial Accounting.

System response

Due to this inconsistency between the General Ledger and the the subsidiary ledger, processing is terminated.

Procedure

Close fiscal year 2007 in Asset Accounting as well.

Am I missing out some steps bcoz the closings have been completed. Kindly advise.

Thanx
