may I know how to set the termination rate calculate duration with 3 decimal in version 6 community?
You can set the number of decimals in the Settings → Configuration
Only issue is currency table on DB remains on only 3 decimals after changing for base system. I suppose that need to be changed on everything, to avoid wrong conversions.
currencyrate field = decimal(10,3)
UPDATED: I tested and best use Dolar or Euro as value 1.000 and not your local currency. And need to update fluctuation on you local exchange directly on DB, because will not show your base currency, on Config->Currencies to update there.
One would think they would have it update there.
