  Can someone please explain the difference between Output and External columns? I can't fathom why "Output"  columns aren't good enough. In other words, what salient feature(s) are hidden in these two types of output columns?

  TIA,

   

  Bill

  Bill,

  Hopefully this will answer your question: http://blogs.conchango.com/jamiethomson/archive/2006/05/23/3984.aspx

   

   

  "these two types of output columns?"

  External columns are not output columns - its important to realise that!
