CountrySubsidenty - BT-39 - so this should be CountrySubdivisionName,
AddressLine - BT-162 - so this should be AddressLine3 which is mapped to AdditionalStreetName, which is BT-36. BT-36 is not commented in the Party-Model so and I could not find it.

• AdditionalStreetName - BT-36 - ??
• CountrySubsidenty - BT-39 - Party.CountrySubdivisionName
• AddressLine:Line - BT-162 - Party.AddressLine3

Correct?

AddressLine No

AddressLine No 1 - StreetName (BT-35 / BT-50)
AddressLine No 2 - AdditionalStreetName (BT-36 / BT-51)
AddressLine No 3 - AddressLine:Line (BT-162 / BT-163)

this is what the cii-writer is doing:

                writer.WriteOptionalElementString("ram:LineOne", string.IsNullOrWhiteSpace(party.ContactName) ? party.Street : party.ContactName); // buyer: BT-50
                if (!string.IsNullOrWhiteSpace(party.ContactName)) { writer.WriteOptionalElementString("ram:LineTwo", party.Street); } // buyer: BT-51
                writer.WriteOptionalElementString("ram:LineThree", party.AddressLine3); // buyer: BT-163
