I am working on an Import Scenario to update the Declared Value to 0 for the boxes in the Packages tab. However, when a shipment contains multiple boxes, the import is creating duplicate package records instead of updating the existing ones.
I tried using Line Nbr. as the key field, but it does not appear to be matching the existing package records correctly. Unfortunately, we do not have a License Number available that can be used as a unique key.
Has anyone successfully updated existing package records through an Import Scenario in this situation? Are there any other fields that can be used to uniquely identify package records, or is there a recommended approach for updating the Declared Value without creating duplicate packages?
Any suggestions would be appreciated.
