title: SSIS 2005: "Append rows to the destination table" is greyed out. Why?
body: <p>In SQL Server 2005, Import Data (SSIS), my desire is to import a text file and have it append to an existing table.   The first time through the wizard on the Column Mappings step I swear the <strong>Append rows to the destination table</strong> radio button was enabled.  But, now, it's disabled (grey) and even re-starting the wizard won't cause it to re-enable.</p>
  
  <p>Is there some secret/magic I don't know about?  How do I get that option to re-enable so that I can append (rather than <strong>Create destination table</strong>)? </p>
