    Exact same file structure but fails when appending data

      Hi

       

      I have a datasource which is a csv file. The file is imported and then published to Tableau Online.

      Then I opened the online data source and chose data->data source->tableau server->append from file.

      I chose the file that contains the additional data.

       

      At the end it fails due to Tableau Data Engine Error: 4: Dataflow::GetColumn: MyComputedColumnName (copy).

       

      The crazy thing is I only have one column MyComputedColumnName. There is no copy (also not hidden or something like that).

      Also when I point to the file that was the original file (ensuring it is exactly the same data) it still fails.


      What could be the case here?
