Hi Luca

Could you please share the Execution Code that you used to achieve this?

@Rickard for that case, I built the automation on the sale.order.line model (not on the sale.order), and I'm triggering the product_id field On UI Change. The code I'm running is something like this:

# Fetch the related product
product = record.product_template_id

if product and product.x_studio_este_custom == False:
# Copy the parameters from the Product.template to the sale.order.line model
record['x_studio_material'] = product.x_studio_print_material
record['x_studio_finisaje'] = product.x_studio_finisaje_1
record['x_studio_material_filter_cat_id'] = product.x_studio_material_category.id
record['x_studio_finisaje_filter_cat_id'] = product.x_studio_finisaje_category.id
elif product and product.x_studio_este_custom == True:
# Reset Custom Values
record['x_studio_este_custom'] = True
record['x_studio_material_filter_cat_id'] = product.x_studio_material_category.id
record['x_studio_finisaje_filter_cat_id'] = product.x_studio_finisaje_category.id
