2067067 - EPM-SA SPM - how the suppliers are assigned multiple diverse classifications

A SPM user has questions regarding Supplier Diversity.
Can you walk me through how the suppliers are assigned multiple diverse classifications as well as how the hierarchy is set up?
Where are the classifications stored (on the vendor master as a field similar to tax ID, company name, etc?)
Is there a specific place in SAP that stores supplier diversity classes?
