Hi Michael:

Odoo uses the External ID (id) field to determine if it is the same record. You can define a naming convention (for example, "product_" + BARCODE) and use this as the value of the external id in the csv file so that the id for the product stays the same across multiple loads. Once you do this, Odoo will update the product if it exists in the system or create a new product if the id is not found.

Hello Juan, or Hola! Could you help me out, where is the option to ignore registry if it already exists?

When I tried to upload a csv with an existing product I got error.

Hi.

When importing from CSV or excel you can test before the data is created in Odoo.

Odoo give the option to ignore the registry when exists.
