Vendor Partner function replication, ordering address, invoicing party

HI SRM Gurus,

Does anyone know if we can replicate different invoicing parties, ordering address or carrier from ECC to SRM?

We want to use these invoicing parties, ordering addresses and carrier etc as partner function in SRM PO.

In MM if we have a vendor master with all these partner functions then while creating a PO, system gives a POP up to select these partner functions. So I have 3 questions-

1. How do we replciate invoicing parties, ordering addresses, carrier etc in SRM?

2. How do we use them as partner function in SRM PO? Does it work same like MM?

3. Can we replicate vendors along with partner functions?

Please provide all customizing steps or enhancements details if any

Regards

Kapil
