    Is there a specific reason for you to do the renaming inside the Loop? Can you do it outside first?

    Hi Thomas,

     

    I have updated the old name as att2 and new name as text,since the Read CSV operator returns default values for row names, when the first row of the file does not convey names of attributes.

     

    I have attached the flow of connected  operator.

    Ok, so your data file comes in with no header. Putting that Rename outside solves your problem then?

    Could you please elaborate.

     

    do mean to remove the rename operator?

    Help will be easier to provide if you include the xml of your process using the </> button.
