M200EES  1.4.  I have a VI job that imports to SO Invoice.  ODBC data source from SQL Ser ver 2005 view.  I want to add another field to the import.  I go to Data Source-Table, available fields tab.  I select the field in the available fields panel and click the 'add' button, but the field is not added to to the selected fields panel.  Does anyone have an idea why?  I could manually edit the SQL statement, but I am reluctant to do that without understanding why the available fields feature is not working.
