We have encountered a sporadic problem where Invoices will print with an incorrect Invoice number. The user will finish processing a shipper, confirm shipment, and let Process manager move the shipper to the 'Print Invoice' stage. At this point there is not an invoice number assigned to the Shipper in the screen. The user will choose the Print Invoice option from the Shipper screen, and the Invoice will print. At this time the Shipper will refresh and have an invoice number assigned. The invoice number that prints on the report is a different invoice number than is assigned to that shipper. If you look at the Event History for the shipper, it will show the 'Print Invoice' task completed, and the invoice number in the Event History screen is the same one that printed on the report, but not the one that is now assigned to the Shipper. The one that printed on the report belonged to the previous shipper that was processed.
