Hi Team,

but while running the process, getting the error as "th attribute att2 specified in the old_name parameter does not exist in the input data."

Additionally, attached the screenshot,kindly have a look.

    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?

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