The reason this would be using the Rounding Difference analysis is that both of these transactions have the same exchange rate. When this happens there is not a difference in the exchange.
And so conversely, if the exchange rate for the two transactions is different, but the currency gross the same, the Exchange Difference analysis will be used.
For more information on Allocations, plesae refer to the Allocations user guides.
This is by design in Access Financials, however we do have a request open with our developers to change the way in which the system works.
Why are differences in my currency allocations going to my rounding code and not to my exchange difference or vice versa?
