ROE means Rate of Exchange. This is the rate that is captured in QBO. If your home currency is CAD and you are posting a USD entry, there will be a box (top left) that has two flags to show you what the ROE is at the date the entry is made. This will show you what the CAD equivalent is for that USD entry. This is important because you will have all your reports in CAD so the ROE will calculate your USD entry into CAD for reporting etc.
When you are trying to make an adjustment to an older entry, you need to consider what ROE you will need to use. Do you use the ROE from the date of the entry or today's date? Depending what you are trying to accomplish that will outline what ROE you use.
Does that help?
