When using the import/export tasks from SQL Management Studio after SP1 has been applied, you can no longer use a query as a data source if it includes data types of varchar/nvarchar. These are no longer recognized from the SQL->SSIS data type mapping, and show up as 200 (varchar) and 202 (nvarchar). nchar also now maps to nvarchar, and binary maps to varbinary, when they previously mapped to their exact data types prior to SP1 being applied.
