changing the capitalize date to the future dated

Dear Gurus,

I have gone through several threads related to the same query before posting this query.

I am changing the capitalize date i.e. ( 30.04.2016)  to the future dated (31.05.2016 ) for the specific assets in order to skip these assets from the depreciation calculation.

Closed fiscal year for the company is: 2014

OB52 settings opened for the April and May 2016

But when we are doing so, we are getting the below Error Message:

01 Book Depreciation

E669 Fiscal Year 2015 is already closed in Financial Accounting.

Regards,

RR.
