Error in AS02 while modifying the costcentre

Question

Hello Gurus,
While modifying the costcentre in AS02 getting an error message stating " You cannot change the depreciation periods". Full description of the message can see below. Please advice how to resolve the issue.
SYST: You cannot change the depreciation periods
Message no. AA662
Asset affected: 000009710401-0000
Diagnosis
Processing terminated because the number of depreciation periods in company code 9440 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 9440. 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.
Regards,
Shekhar.

Hi,
the following settings are relevant:
1) in the depr.key: T090NA-XDAILY
2) in the asset: ANLB-PERFY
ANLB-PERFY = 365  and  T090NA-XDAILY  = X          => correkt
ANLB-PERFY =  12  and  T090NA-XDAILY  = initial    => correct
The Other constellations are not correct and lead to AA662.
Please mark: ANLB-PERFY is set at the point when you create an asset and
it can't be changed later in customizing.
Most probably you have ANLB-PERFY = 365  and  T090NA-XDAILY  = initial.
Solution:
1) Use another depreciation key where T090NA-XDAILY  = X
2) Make a transfer to another asset where ANLB-PERFY =  12
3) To change ANLB-PERFY per ABAP or debugging is not the from SAP Recommended way, but it is an easy solution and it works.
