The behavior depends on the order of document upload:
When the Commercial Invoice is uploaded first:
The system extracts the products from the Commercial Invoice for classification.
If a Packing List is uploaded afterward, its products are extracted but not classified, and they do not appear in the Classification screen.
When one or more Packing Lists are uploaded before the Commercial Invoice:
The Packing List is classified, and its products appear in the Classification screen.
However, if a Commercial Invoice is uploaded later, it will also be analyzed and classified, which may result in duplicate products if both documents refer to the same items.
Recommendation:
Clients should be advised to upload the Commercial Invoice before the Packing List to prevent duplicates and ensure proper classification.
