Hi Colby,

You will have to make a small customization for adding ASIN as this feature is not available by default in odoo 17.

Enable product variants inside Inventory -> Configuration -> Settings

Now you may add a Field for ASIN using a custom module or from Studio, If you prefer a custom module, check the code below or Add field from studio

from odoo import models, fields

class ProductTemplate(models.Model):

    _inherit = 'product.template'

    asin = fields.Char(string="ASIN")

class ProductProduct(models.Model):

    _inherit = 'product.product'

    asin = fields.Char(string="ASIN")

Now for each products, you can add a unique ASIN and save it.

Thanks
