Error in asset after change of FYV to 13 period

Question

Hi,
We changed the fisical year variant to 13 period from 12 period in year 2006 i.e. september is two period ,one on 18th and other on 30th.
Now we are not able to do master data change i.e. AS02 to change the depreciation Key and even we are not able to ABZ0.
Please find the attached message we are getting while doing the above transactions.
Thanks in advance and will appreciate your help.
SYST: You cannot change the depreciation periods
Message no. AA662
Asset affected: 175030000034-0000
Diagnosis
Processing terminated because the number of depreciation periods in company code 175 has been changed. However, you cannot change the number of periods in your live (productive) system.
Procedure
Change the depreciation periods back to the original value in company code 175. The number of depreciation periods is determined by the fiscal year version and the use of half-periods. At least one of these parameters was changed.
If you want to change your system so that you can now work with half-periods, you have to use depreciation keys with time-dependent period control in that company code.
If you need to make general changes to the number of periods for calculating depreciation per fiscal year, you will have to consult your system administrator.

Hi Alok,
My 2 cents please check the OSS notes, also while changing fiscal year we must be very careful.
do refer the following oss notes : 132804 (Fiscal year change takes planned depreciation )
AA669 upon fiscal year change and AW01 (196651, 79195)
notes  46905 & (406960)Differing fiscal year variant in derived depreciation area 
hope this are helpful.
Please assign points as way to say thanks.
