Maybe you can post your issues in attunity forum too. ODBC operator for tpt is certified to work only with the DataDirect/Progress ODBC drivers. Others may work but may produce unwanted results.
You need to install:
- MS SSIS Connector for Teradata (note, different connector rel. exists for SQL Server IS versions)
- Teradata ODBC (32 and 64) (metadata/schema interrogation)
- Teradata TPT Base and Stream
See SSIS and Teradata paper at http://www.teradata.com/Resources/White-Papers/Mic
