Hi,

The error you’re seeing happens because standard_price is a product template field, not a variant field, and Odoo doesn’t handle updates well when you try to import it through product.product (variants). That’s why creating new products works, but updating existing ones with just the internal database ID fails and throws the “tuple index out of range” error. The correct way is to export products from Products (product.template), include the “ID” or “External ID” along with the fields you want to update (like standard_price), and then re-import that file. If you really need to update variant-specific fields, you should work with Product Variants (product.product) but identify them using either External IDs or a combination of template and attribute values rather than relying on the raw database ID. This way, Odoo knows exactly which record to update and won’t throw errors.

Hope it helps.

I have tested with as simple dataset as follows:

I have made an export and tried to import the same data, but I encounter the same error every time.

Can you please provide the details or sample sheet here?
