To clarify Doug's point about the Terms code, the extra space can cause 'confusion'. It makes the field 7 characters long, when the maximum length of that field is 6. Perhaps we should be giving a more appropriate warning, but the end result is that for larger import files there will likely be some sort of error. I have seen this behaviour before - see our second posting and the '13-character' invoice number field.
Though we have not seen any problems with having the Due/Discount date field as 'Default' values, Doug's point about including them anyway in the import file is also well taken.
