   { FIXED [Customer ID] : MIN([Order Date]) }
   

8. How would you identify customers with no orders in the last 90 days?
   Compare latest order date with today.
   Example:

   DATEDIFF('day', MAX([Order Date]), TODAY()) > 90
   

9. How would you create a Pareto chart in Tableau?
   Combine bars and cumulative percentage line.
   Example:

   RUNNING_SUM(SUM([Sales])) / TOTAL(SUM([Sales]))
