I try to filter the product_id field in sale.order.line to get only products, that have the same company_id as the logged in user selected in the top right dropdown, when the multicompany feature is active.

How can I add a domain that filters that?

I tried a lot of solutions, but nothing works right.

<field name="product_id" domain="[('company_id', '=', user.company_id)]"/>

<field name="product_id" domain="[('company_id', '=', env.user.company_id)]"/>

thanks

PS: the big problem is, when a user have multiple company in the settings

EDIT: It's possible with the security rule on the "product.product" object, but then it's for every model that use product_id.

I only want it for the purchase.order.line
