Asset Retirement with Customer

Hi

I have posted Asset Retirement with Customer using Transation Type 260 (retirement of current year acquisition with revenue).

I had posted depreciation upto period 7 and sale is made on period 8.

When posting the retirement, the current period depreciation for period 8 is posted to accumulated depreciation.

How this can be corrected and how to post depreciation for the current period while using Transaction F-92.

Thanks in advance
