Denodo throwing error "The field properties can only be specified for derived fields" on a job while altering column description of columns

Question

I have created a job in denodo to update column descriptions of all the views. All the information related to views are stored in glossary only.We have created a view on top of this glossary datasource.We are then creating a view which contains a column having the script(alter statement to alter column desc). This column is fetched in our job. When we are executing this job(selecting this column only), it should execute the alter statement. Unfortunately job is getting failed with felow error: "The field properties can only be specified for derived fields"

I want the job to execute and need to update column description

Answer 1

This is the alter statement which i have used previously. But the job fails with the error message "The field properties can only be specified for derived fields." Please let me know how to fix this.
