This is designed for our Contractor Companies to help map out relationships they have at sites with the Client and their own Sub-contractors.
This can help you as a Supplier Administrator to show existing relationships.
It will be viewable by any of your Supplier Administrators, and those companies you associate.
Additionally the Client themselves will also be able to review this for future information and support.
However this is an optional feature and not all clients have this enabled in their Supplier Portals
It is configured by each Client.
