Exchange Rate Price Difference

Hi All,

I have one query regarding the Exchange Rate Price

Example: In My Scenario, I am using the Exchange Rate Currently USD to AUD

Here i can define the Exchange Rate for USD to AUD as 1.37, So Currently our system is automatically calculate the AUD to USD(0.73), But in my Scenario actual my value is for AUD to USD is 1

So is there any exchange price adjustment option is there/ Is there any option to define the Value

Thanks
