If customer provides a site in the site list, with Supplier Name as "AB" and Subcontractor Name as "XY" then, the site is owned by "XY", but the customer has a relation to that site owned by "XY" through the supplier "AB" only.
It's like, partner "AB" will be supplying a particular part to the customer, but the part is manufactured from the site of "XY”, where "AB" has given a contract to "XY".
So, for customer, "AB" is a tier n supplier and "XY" is a tier n+1 supplier. By providing in the manner, if the site owned by "XY" is affected, customer will get to know.
The Subcontractor "XY" will show up as tier n+1 supplier in supplier listing page. Also, the site name generated will have the format(nomenclature) as Partner Name - Subcontractor - Country State City.
