BP and vendor Partner function

Hello,

We have been using 3 tier vendor structure and are migrating to BP structure in HANA. Our current process is to create multiple "PO vendors" and assign it to the same head quarter vendor, when there is a requirement to send PO to a different address. The specific PO vendor number is then entered/selected while creating the PO. We use standard requisition process to create PO.

Is there a functionality in the new BP structure to get the same results without creating additional vendor master for multiple ordering addresses? or do we need to create new PO vendors and follow the same logic of entering specific PO vendor in PO?

I understand that multiple addresses can be maintained for the same BP. I am interested in understanding how these addresses can be pulled in to a PO without creating additional vendor numbers just for ordering addresses, if that is possible.

Thanks,

Vinod
