Above the chart is AGG (average number of customer hours cost center), which is SUM([Direct Time In Hours])/[numberofclients].[Sum unique clients cost center]. Sum unique clients cost center is in Tableau with the following calculation: SUM({FIXED [Year], [Month], [Cost Center Name]: COUNTD([Client])}) I want the tableau to have a row per cost center per month, and all the data comes from the numberofclients table. Can you convert this to an MSSQL database query?",
