Check the Vertex tax system constants to ensure that the Vertex interface is activated.
Check address book revisions (P01051) country code for the address book entry (CTR). The value in this field must be the same as the value entered for the country code in the Vertex tax system constants file (P7301) for the United States (VVUS) or Canada (VVCN). Example, if the country code for the United States in the address book is blank, then the country code for the United States in the Vertex constants file should also be blank.
