3427668 - Changing depreciation key results in error AB720/AB721

Changing depreciation key results in either error below:

• AB720    Enter a depreciation key with 'depreciation by days' such as &1
• AB721    Use a depreciation key without calculation to the day, such as &1

S/4Hana Cloud

In the Manage Fixed Assets app, select a depreciation area and try to change the depreciation key and save. 

The errors are triggered if old key has depreciation to the day and the new one does not, or vice versa. 
It is not possible to mix keys with and without depreciation to the day set once there has been depreciation posted. 

• If the wrong key was selected, then reverse the acquisition, the asset will not get inverse depreciation to offset the already posted depreciation. Then create a new asset with the desired depreciation key.
• If you need to use both keys, then create a new asset with the desired new key, and transfer the value to the new asset. 

Ensure to do a depreciation run once the changes have been made.
