Is there anything you enjoy more in managing your Magento store than restricting role access?
Either way, here’s the good news: Advanced Permissions for Magento now allows to define user roles even more precisely. After the latest update the extension enables you as the super-admin to allow sub-admin users to manage only the orders that contain the products assigned to their role.
If you’re already using Advanced Permissions, get your updates. If you’re not using the extension yet, take a look at all the possibilities it offers.
