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 Append rows to the destination table radio button was enabled. But, now, it's disabled (grey) and even re-starting the wizard won't cause it to re-enable.
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 Create destination table)?
