Errors can include
Unable to Create Shipment:Notification no. 0 Severity: ERROR Code: 6573 Message: UnitPrice - Invalid amount in Commodity 1 Source: ship
Unable to Create Shipment:Notification no. 0 Severity: ERROR Code: 6571 Message: CustomsValue - Invalid amount in Commodity 1 Source: ship
The error (CustomsValue - Invalid amount in Commodity 1 Source: ship or UnitPrice - Invalid amount in Commodity 1 Source: ship) from FedEx occurs when the item value is zero or negative, often due to the discount being higher than the item price.
For example:
Item A
Price: £38
Discount: £46
VAT: £8
In Mintsoft, the discount is subtracted from the price, while the VAT remains separate. When generating the shipment, FedEx sees 38 - 46, which causes the error. To resolve this, ensure the discount matches the price of the item.
