I want to add non stock consulting item(See below figure) to invoices screen details tab when creating prepare invoice from shipments screen. I tried override shipment screen “CreateInvoice” action as well as fire Row Persisted event and override Persist method in Invoices screen too but unbale to do. I saw when fire Row Persisted event or override Persist method just executing(looping) no end point. Please give me any answer or suggestions.
