Hi,
In this update, we've made it mandatory to keep Equity/FixedAssets/LongTermLiability type of accounts in base currency. So, the currency field is disabled for such type of accounts. I hope, when you changed the base currency, those a/c's currencies are changed as well.
The group reporting currency is used only when the company's functional currency is different from the group/parent company's currency. If so, you can define the exchange rate to group currency in the currency master view. This will be used to generate the reports for group company reporting. If you don't have such a setup, then you may leave the group currency field undefined or keep it same as the base currency.
And in this release, all the issues you had reported have been solved! Please give them a try and also please go through the sales and purchase modules in the sample company. We're further improving the performance and other features there, but the view designs will be similar. We'll also integrate Inventory module by Nov end and we're further working on many report related improvements, adding new reports(like cashflow/more comparison reports,...) to the accounts module.
Your feedbacks on any of the features are highly appreciated and can be incorporated into the system in the early phase.
Thanks and regards,
Prashant
