Which exchange rate is selected when interco time posting

Hello,

We want to know where the system takes the exchange rate when there's an interco time posting. In the example, we see that the transaction currency is CAD, and the company code currency is EUR. However, we don't see the exchange rate.

If we calculate the exchange rate, we have 0.68735

However, when we look at the app Currency exchange rates, we don't see this rate:

We have defined the posting date in the conversion settings:

Thank you

Elizabeth
