Our local currency is TWD and we need to convert document currency in sales order from EUR to the third currency (e.g. USD) when executing BW query in BEx Analyzer. Currently we only have exchange rates for all currencies to TWD in exchange rate table. Except for defining exchange rate of EUR to USD in exchange rate table, is it possible to convert EUR to USD (e.g. convert EUR to TWD first and then convert TWD to USD)?
