I would also appreciate an explanation for what the output is telling me, that is not provided anywhere. I am attaching the csv file and .rmp file for your reference.

    Hi,
    what happens if you right click on the operator and use the Show Problem option?

    Hi @Booram ,
    so what exactly is unclear about the error messages? They seem very straight forward?

    Cheers,

    Okay but how to change that data type,  can you please try running the workflow and from your end provide a workflow without any error.

    Hi,
    there are operators like Parse Numbers or Nominal to Numerical etc. They are in the folder Type Conversion in your operator tree.
