We recommend that you use the following elements for outbound Accounts Receivable (AR) invoices:

Supplier Address Line 1 (Invoice/AccountingSupplierParty/Party/PostalAddress/StreetName)
Supplier City (Invoice/AccountingSupplierParty/Party/PostalAddress/CityName)
Supplier City Post Code (Invoice/AccountingSupplierParty/Party/PostalAddress/PostalZone)

If you cannot use these, you can use up to 2 Supplier Additional Address Line (Invoice/AccountingSupplierParty/Party/PostalAddress/AddressLine/Line) elements.

For inbound Accounts Payable (AP) invoices, the KSF (FA3) format uses 2 generic free-text elements to model address lines. Therefore, you can only model these lines for inbound AP invoices.
