Hi! Where do I see which account is used for currency revaluation? I can see on all past transactions which one we use, but I need to know where that account comes from. It is not a special account so I guess there will be a setting somewhere.

System account or if you have set up foreign variance rule you can use another accounts

But the one we use, I can see that it is was manually added.

Go to Setup > Accounting > Foreign Currency Variance Posting Rules
