our local currency is USD. we post a miro invoice with 50 GBP in Nov.1.2012 , exchange rate 1 GBP=1.5 USD, thus 75 USD.
in Nov.5, we post a credit memo with 5 GBP, exchange rate 1GBP=1.6 USD, thus 8 USD.
My requirement is: can system able to automatically use invoice date exchange rate (in this case 1.5 USD) for credit memo?
thus I expect, 5*1.5=7.5 USD in my credit memo.
Thanks
