Hello,
Yes, I understood that.
And I told you to tweak your ACL to not let the vendor see the manufacturer ; since it's a value provided by the template, you do not need to vendor to see/edit it.
Even if the vendor do not edit it, the value will be taken from the template, so it will become a "forced value".
