Does anyone have a saved search that shows the amount remaining for all invoices related to a sales order? Essentially all of the related invoices tied to a Sales Order and their balance summed? I want to put that on the Sales Order as a field. I felt like that should be easy but I am beating my head against the wall. Screenshot would be greatly appreciated 🙂
