Your company uses only book depreciation and you activate the new depreciation engine. The book depreciation key Z010 which is currently used by an asset should be changed to Z020. The asset depreciation started two years ago, and depreciation for the current year has already been posted for the months of January, February, and March (monthly depreciation run). The change should take effect from April 1st.
How can you implement this change? (Choose two.)

A. Undo the depreciation postings for the asset in the current year. Then call the Depreciation Areas screen in the asset master and change the key from Z010 to Z020.
B. Call the Depreciation Areas screen in the asset master and assign the key Z020 with validity start date of April 1st.
C. Call the Depreciation Areas screen in the asset master and change the depreciation key from Z010 to Z020. Also change the ordinary depreciation start date to April 1st.
D. Create a new asset referencing the asset you want to change. On the Depreciation Areas screen, select depreciation key Z020. Then post an asset transfer from the existing asset to the new asset.
