At which levels do you choose between direct and indirect quotation?

[Reference: SAP Help Documentation states, "For each exchange rate type, you define whether the exchange rate is maintained as a direct or indirect quotation.", Company Code (C), While the quotation method is defined at the exchange rate type level, the company code determines which exchange rate types are used for specific processes (e.g., valuation, translation)., Example: A company code with local currency EUR may use exchange rate type "M" (direct quotation), while another company code with USD may use a custom type configured for indirect quotation., Configuration Path:, Assign exchange rate types to company codes via Financial Accounting > General Ledger Accounting > Periodic Processing > Valuation > Assign Exchange Rate Types (App: Assign Exchange Rate Types)., Why Other Options Are Incorrect, Country (B): While country settings influence currency assignments (e.g., local currency for a country), they do not directly configure direct/indirect quotation., Client (D): Exchange rate types are client-dependent, but the client itself does not define the quotation method., , ]
