Adding serial numbers to a purchased products allows you to assign a unique code to each received item, meaning you can later assign the same number on a sales order (SO). This gives you traceability from shipments to customers, to receiving from suppliers.

If serial number tracking is enabled for a product and a purchase order (PO) or outsourced purchase order (OPO) is created for the product, a Tracing column will be added to the Items table.

If no serial numbers have been added to the products you're receiving, the Tracing column will display an exclamation mark icon for the item row.

You can assign serial numbers to a PO or OPO when an order row is Not received or Received, but the amount of serial numbers can't exceed the row quantity.

Adding serial numbers to purchased products

  1. Open a PO or OPO, and click the Traceability icon on the item row.
