Hi, thanks for the your reply, this code you giving is also not working, on  xml it accepts but on python is not coming I'm trying to add restrictions to some companies on creating products on sale order, is there is any other way to achieve that please. 	​	​	​	​	​	​	​	​	​	​	​	​	​	​	​	​	​	​	​	​
@api.model
def _get_view(self, view_id=None, view_type='form', **options):
    arch, view = super()._get_view(view_id, view_type, **options)
    active_company = self.env.company
    if view_type == 'form' and active_company.company:
        for node in arch.xpath("//field[@name='order_line']//field[@name='product_template_id']"):
          #i tried fields.set and node.set still not working.
 node.set('options', "{'no_create': True, 'no_create_edit': True, 'no_open': True}")
    return arch, view

Hi,

fields_view_get no longer exist in Odoo 17.Instead of that use _get_view and try the below code:@api.model

def _get_view(self, view_id=None, view_type='form', **options):

       arch, view = super()._get_view(view_id, view_type, **options)

       if view_type == 'form':

               for node in arch.xpath("//field[@name='order_line']//field[@name='product_template_id']"):

                    field.set("options", "{'no_create': True, 'no_create_edit': True, 'no_open': True}")

       return arch, view

Hope it helps
