The currency while creating the supplier was in USD as default. I haven’t changed it whilst making the payment. Yeah, the payment currency option appears opposite. A bug maybe?
In your payment screenshot above - change the unit price to 16,000 so the amount = 16,000 BDT and the exchange rate to 0.0125 then the USD will be 200.
Don’t you think the unit price which automatically comes in the unit price field as soon you spend money should show default currency account - USD instead of BDT and the BDT should be instead the USD field in the right side?
In that case, it should show 16000BDT instead of 200BDT. This is not appropriate user interface. Either the fields should be blank or it should pull out the right numbers.
