Depreciation Area and Local Currency

Hello Experts,

I cannot find any threads treating the following points.

Business wants to get GL balances in CAD (1st local currency) and USD (group currency). However, from AA perspective business does not require to get asset valuation in USD. In this case, can we get rid of the parralel depreciation area in USD ? (copy APC and depreciation terms from 01)

Until now I though it was mandatory to get the same level of valuation between FI and AA but as this parallel valuation will not post to any ledger, I think I was wrong.

Can you confirm my statement ?

Thank you all for your support.
