Calculated Field
          Use a Calculated Field extension type if you require additional fields (non-table fields) in the data to be published to Data Lake. 
         
         Calculated Fields added as an extension to a table cannot be used in sessions, reports, etc.
Examples:
- Aggregations of table fields (average, sum, etc.)
 - Results of called library functions
