When a PO export file is created for POs using a u_nv_po_format_type_a type Order Method, this file will now include the selling code of each SKU on the order, for SKUs that have selling code(s) defined for them. If a primary selling code is defined for the SKU this is the selling code that will be included in the export file. If there are selling code(s) defined for the SKU but none flagged as the primary, then any of these selling codes may be included in the export file.
