If you want to aggregate sales data, which measure would you create using DAX?

Creating an aggregation of sales data often means summing up the total sales figures over a specific period or category. The SUM function in DAX is specifically designed for this purpose. When you utilize SUM, it allows you to add together all numerical values within a specified column or table, which is particularly useful when you need to compute total sales revenue.

While other functions like AVERAGE, MAX, and COUNT serve their own specific roles—calculating the average, finding the maximum value, and counting entries respectively—they do not directly provide the total sum of sales data. Each of those functions has a different focus that would not yield the same result as summing the sales figures. Therefore, using SUM is the most appropriate measure when the goal is to aggregate sales data to provide a total figure.
