Calculated Measures TotalSalesInMillions=CONCATENATE(R", CONCATENATE(FORMAT(CALCULATE(ROUND(SUM (FactSales[SalesAmount])/1000000, 0)), "#,###"), "M")) Creates a string that encloses the sales amount in a Rand sign and an M for millions. The value is rounded to a million. SalesPrevYr=CALCULATE(SUM (FactSales[SalesAmount]), DATEADD(DimDate[DateKey], -1, YEAR)) Calculates the sales amount for the previous year. YoY =IF(SUM(FactSales[SalesAmount]),(IF ([SalesPrevYr],(SUM (FactSales[SalesAmount]) - [SalesPrevYr])/[SalesPrevYr], BLANK())),BLANK()) Calculates the year-over-year growth if the current year and the previous year have sales values. The formula returns BLANK() if the previous or the current year has no value.
