MM-SUS scenario: Purchase order doesn't create in SRM SUS

Hi,

We are implementing MM-SUS scenario: Service Procurement Scenario.

I’m trying to replicate purchase orders from my ERP system to SUS using XI interface “PurchaseOrderERPRequest_In_V1”

.

When PO xml arrives to SUS, it returns the error messages:

Vendor:

         BBP_PD 147 Enter a country for partner  0000028362 with type ‘Vendor’

         BBP_PD  537 Name fields of partners/addresses must be filled; check

Company:

         BBP_PD 147 Enter a country for partner  P121 with type ‘Sold-to-party’

         BBP_PD  537 Name fields of partners/addresses must be filled; check

Can you help us solve this errors and create PO document?

Thanks in advance

Maria
