Field Service with Operating Units

This module links Field Service orders to Operating Units, a way of splitting data between different branches, regions or business units inside the same Odoo database.

• On the Field Service order form, a new "Operating Unit" field appears right after the order type. When a user creates a new order, this field is filled in automatically with that user's default operating unit.
• A security rule is added on Field Service orders: users can only read orders whose operating unit is one of the operating units assigned to them, or orders that have no operating unit at all. The rule is read-only, so it does not by itself grant or block creating, editing or deleting orders.

The module touches the fsm.order model and its form view. It depends on the Operating Unit and Field Service modules, so those must be installed for it to work. No new menus, reports, emails or scheduled actions are added by this code.
