   There are 3 fields that go into the Excel Input Transform.  The Excel file 
has 3 fields to output itself.
   Notice when you check the dummy step output shows 3 fields only from the 
excel file.  However, if you "Show Output Fields" it shows 6  (the three from 
the data grid, and the three from the Excel file).  It would be great to have 
the option of letting those incoming fields pass through, or if that is not 
possible, to at least remove them from the stream that comes out of the Excel 
File Input.  As is, if you have a Select Transform, it will see A, B, C, from 
the datagrid and the others from the excel file, but will mess up and throw 
errors because somehow it does not have real access to A, B, C.
   
   Generally I like the option to either let incoming fields flow through or 
not.
   This case is a bug because it looks like the transform did not intend to let 
those incoming fields flow out, but let the metadata for them flow out anyway.
