ECE versus Currency Conversion

Dear all,

do you have information about ECE and currency conversion (i.e. from accounts' secondary do primary currency or from system currency to account currency)?

First of all is the concept at all supported by ECE?

And second -- did someone manage to configure it working?

At my environment I have receive rather not correct (from business perspective) results:

* The account has currency = USD, system currency = USD and offer/balance impact currency = EUR.

* ECE prices the usage event in EUR and so it is stored in event's balance impact

* however accounts currency balance is impacted (including due amount in item) as the balance have been calculated in USD.
