There appears to be a difference between v8RC1 (saas5) and v8 (saas6) in multicurrency setup as it seems impossible to set exchange gain and loss accounts under settings/configuration/accounting. After clicking on apply the set account numbers disappear and it seems that they have not been set.
All the usual user settings (multicurrency, sale pricelist, purchase pricelist) have been set, and the euro currency (rate=1.000) has been set to base.
I have the same problem. As I look in the account_config_settings in Postgres, there are no fields defined for income_currency_exchange_account_id and expense_currency_exchange_account_id. I may later add these fields in Postgres to see if it works as a temporary workaround.
Is it really possible that such a critical feature like this can suddenly 'break' between v8RC1 and v8 'stable' ?
When V7 came out there were many issues kind of like this, so I'm not so surprised. Not sure how it could happen between V8RC and V8, though.
v8 has been trailed for 9 months, issues like these, if they are real issues and not just the results of some other misconfiguration (please someone tell me that it is) should have been fixed at v8RC1 at the latest.
