Situation:
1. I have a user
2. I want administrator access for user at Company B
3. I want to restrict access for user at Company A
I have searched far and wide and the only thing I got is to make record rules with the company_id set. I tried it and maybe being a noob, I couldn't make it work. Either I just get the error message or I get an odoo error. I'm accessing the Technical tab and experimenting with this but having trouble. Any help here to help me understand how this works?
