Use this dialog box to refresh the currency values of a project forecast. When using multicurrency budgeting and forecasting you have a choice of using the same currency rates throughout the period of the forecast or change it if the necessity arises. Once a change is done you are able to refresh the existing budgeted/forecasted values for the forecast.
To make these recalculated values useful in a forecast you need to create a new snapshot capturing the changed amounts and connect it to your forecast.
