I was wondering as I am new to the User Pro Version if you can setup access to Product Level so multiple vendors can be setup as user so they can monitor and update information on their product lines and only their product lines.
If that is possible, please let me know how to setup and if not would be a great feature to the User Role Pro Version.
Look at “posts/pages edit access restrictions” add-on. It has Allow – ‘Own data only’ option. It works for any custom post type too. So product owners will see and can edit at back-end just there own products and related orders only.
This restriction is possible to set as per user via user profile, as per role via role editor.
May be it will be suitable to resolve your task, but may be it’s better to look for a special vendors plugin too.
