Create Reusable Functions and Calculations in a Workbook
Use calculated data elements to provide reusable functions and calculations that you can add to multiple visualizations in a workbook. For example, you might use a BIN function to classify AGE values into four buckets: 0 to 20, 21 to 40, 41 to 60, and 60 plus.
Calculated data elements are stored in the dataset’s My Calculations folder and not in the workbook. Workbooks have a My Calculations folder for each dataset used (whether joined or not-joined).
