Reverse asset retirement from last year

Hi,

One asset was retired in Dec 2009.

Now we want to take the asset back in our books and then sell it to another customer.

Problem is: i am not able to reverse the retirement from 2009.

Also tried using post capitalization ABNAN, but system gives error message "Fiscal year 2010 is incorrect for post capitalization of asset"

Asset Acquisition date is in 2008.

Fiscal year 2009 is closed and can not open

Can anyone help me out with this problem?

How do i reverse the retirement in 2010??

Regards,

Smile
