  • Private - If selected, the values of variables and arguments are no longer logged at Verbose level.


  • InvalidColumns - The list of column names that could not be matched with the ones supplied in the Mapping property, stored in an IEnumerable<String> variable. This field supports only IEnumerable<String> variables.
