Fixed Asset Constants change

Hi,

The company I am working for has their fixed asset constants setup for Accumulated Depreciation, Depreciation Expense and Revenue depreciation defaults set to Default.

What do I need to consider when changing the Accumulated Depreciation, Depreciation Expense and Revenue depreciation defaults from Default to Responsible BU?

I understand once I make the change, all new assets created will start using the Responsible BU on the asset master in conjunction with the default coding (P12002) for the obj and sub.

I would need to check to ensure all assets currently in the system will have a valid account for Accumulated Depreciation, Depreciation Expense and Revenue depreciation after the change.
