Vendor Hierarchy in MDG

Hello experts,

I have a requirement for making a replication of Vendor Hierarchy, how it is on ECC, i need to produce the name results in MDG Supplier/Vendor.

I do know that MDG works on Business Partner functionality, which is different.

My question is, do we design from scratch Vendor Hierarchy or extend it.

Also some inputs from MDG BP perspective, why is it different

thanks and regards

Abhishek
