CSV Import of Sales Order > Error Message: Please specify either a terms parameter or a paymentmethod parameter in the request but not both

When you import a Sales Order, the Terms and Payment Method cannot be mapped simultaneously.  You can only map one of those fields in the Field Mapping page.

Please note that if you enter Terms on a Sales Order, an Invoice is automatically generated when it is billed. If you enter a Payment Method, a Cash Sale is automatically generated when it is billed.
