## When Should You Use Sum and Sumx in Power BI?

Power BI is a powerful data visualization tool that enables users to create engaging, interactive reports and dashboards. One of the most commonly used functions in Power BI is the Sum and Sumx functions. These functions allow users to quickly and easily calculate and analyze data. In this article, we’ll discuss when to use Sum and Sumx in Power BI.

The Sum and Sumx functions are used to calculate the sum of a set of numbers. The Sum function takes a table as an argument and returns the sum of all the values in the table. The Sumx function takes a table and an expression as arguments and returns the sum of the expression for each row in the table.

The Sum and Sumx functions are useful when you need to quickly and easily calculate the sum of a set of numbers. For example, if you need to calculate the total sales for a month, you can use the Sum function. The Sumx function is useful when you need to calculate the sum of an expression for each row in a table. For example, if you need to calculate the total sales for each product, you can use the Sumx function.
