Ok thanks Ryan. So what happens when the edited $690 order gets marked Payment Received? There would actually be an attempted refund processed by the system? In this case, the original $1244 order was created using the Add Order functionality from the app, then edited down to $690. So there is no payment in transit (the customer has not even been notified of the first order) and the desired outcome is just to have received $690 with no refunds necessary when the $690 order is marked received.
Is it possible then for you to make the pending payment field editable to accommodate these different scenarios (not as easily editable as the test fields perhaps, but maybe the user needs to hit an edit icon next to the figure or switch a setting on first)? Or a checkbox on the Edit Order page where you can toggle on/off that the pending payment amount should be updated to the new total or left the same?
