Hi,

To import Product Packagings for existing products, you should at minimum include a field that uniquely identifies the product (preferably the Internal Reference or External ID rather than the product name), along with the Packaging Name and the Contained Quantity (qty). Optional fields such as Barcode, Sales, Purchase, and Company can also be included if they are relevant to your setup. The easiest way to determine the exact field names expected by your database is to export a few existing packaging records from Inventory → Configuration → Product Packagings and use the exported file as a template for your import. This ensures that the column headers match the fields Odoo expects and helps avoid mapping issues during the import process.
