In this instance, when you click update, a journal will be created on the given date for the delta between the original and the current data and an additional time and date stamp will appear, with a new deep link out to the additional journal:
This will trigger an adjustment line in the schedule so that you can see the transactions being released in the correct period and also still reconcile back to Xero. For more information see this helpful article on How the adjustment line works
