First, activate Product Packagings:

Next, define the barcode for the Product on the General Information tab and add each additional barcode on the Inventory Tab:

When this product arrives or is ordered or needs to be moved in the Warehouse, you can scan any of the following barcodes to pick it:

• 1238550602668
• 2238550602668
• 3238550602668

On Purchase Orders for this product, you can select (if you wish) the packaging representing the barcode you expect to receive, but this is optional (you can purchase any package in this situation, and all barcodes will still work if you select one that the Vendor does not use).
