Warning: Cannot apply name to column at index (because this name is already in use)

      Warning: Cannot apply name to column at index (because this name is already in use)

      Hi all, interested to know what this warning means - could anybody point me in the right direction?

      Source Code

      1. WARN Cannot apply name to column at index 3 because this name is already in use.


      If it helps, the organisation of the load, and log are attached.

      Cheers,

      -Phil

      I guess you are trying to rename columns in the FieldTransform right before the TableNormalization or maybe in the TableNormalization itself.
      One of the new column header probably already exists.

      It would be helpful to see the transforms or at least the names of the transforms in the flow graph as well as the log to identify the right transform.
