only one GL account for depreciation expense?

Hi,

Currently, my client is setting up new sap system.

They have about 5-6 asset classes. But they want to have only 1 depreciation expense GL account with separate accumulated depreciation GL accounts by asset classes.

Simply speaking, the only depreciation expense GL account may be able to be assigned to AO90. But Is there any risk when we have the only 1 common GL account for depreciation expense for 5-6 asset classes?

Thank you,
