Hi,

There are two approaches:

1. Use a computed domain on product variants

Override the product template view to show only active variants in dropdowns.

Example:

<field name="product_variant_ids" domain="[('active','=',True)]"/>

This doesn’t prevent creation, but it hides archived variants from selection.

2. Prevent automatic unarchiving via code

Override _create_variant_ids in product.template:

from odoo import models

class ProductTemplate(models.Model):

    _inherit = 'product.template'

    def _create_variant_ids(self):

        # Prevent archived variants from being reactivated

        existing_variants = self.product_variant_ids.filtered(lambda v: not v.active)

        super(ProductTemplate, self)._create_variant_ids()

        # Re-archive any variants that were previously archived

        existing_variants.write({'active': False})

Hope it helps.

Hi,

You should removed this archived variant from the product template before created the new one.

Regards!
