remove 1 month of depreciation figures

Dear experts

I have run depreciation run for 12 months but would like to reverse out the depreciation figures for 12th month due to some business requirements.

Writeup will meet this but this can only be done in the new financial year. We want this to be done for current Financial year under Period=13.

The accounting posting is: DR cum-depreciation

CR Depreciation

Unplanned depreciation (ttype 6xx) cannot be done as it gives the reversed postings.

Writeup (ttype 7xx) can only be done in new FY for prior year.

Is there any standard SAP transaction which can achieve my required posting?

Really appreciate your inputs as it is affecting my year end. Thank you.
