Before new vendors can be created (either manually or imported), the required fields such as Terms and Control Account Sets must first be created.
If you intend to use MultiCurrency, ensure that this is properly defined in the Comapny Profile and on the Control Account Sets.
You don't import the Currency code, but rather this is set via the Control Account Set. If that field was exported as a column from the initial company, set the import template to Skip this column by replacing the Currency Code column with a Filler (the button in the middle of the fields screen, between the arrows).
