2024年4月25日 · The SUMX function takes as its first argument a table, or an expression that returns a table. The second argument is a column that contains the numbers you want to sum, or an expression that evaluates to a column.

2025年3月24日 · Returns the sum of an expression evaluated for each row in a table.

2019年10月28日 · SUMX is an iteration function in Power BI that works on a row-by-row calculation per the given expression or equation. This function considers each row at a time and applies the calculation. It will not concentrate on the entire column, unlike the SUM function.

2023年12月22日 · Summary: The Difference Between SUM vs. SUMX in Power BI. In summary: The SUM function is used to calculate the sum of values in one column. The SUMX function is used to calculate the sum of an expression that can include multiple columns in a table and can be used with the FILTER function.

2024年1月31日 · What is the SUMX Function in Power BI? The SUMX function in Power BI is a powerful DAX function used to calculate the sum of an expression that is calculated for each row in a table. This function is important because it allows for more complex calculations than a …

2023年1月20日 · Unlike SUM, SUMX is capable of performing row-by-row calculations and iterates through every row of a specified table to complete the calculation. SUMX then adds all the row-wise results of the iterations of the given expression. A typical SUMX function looks like this: SUMX (<Table>, <Expression>)

2019年8月29日 · Sum and SumX both are functions calculating aggregation. However, the SUMX calculates the aggregation on an expression resolved from a table which can be dynamically calculated as well. SUMX is a generic and powerful function, that is why we see the usage of …

2020年7月24日 · quick question: If I want to sum a subset of a column, for example the sum of the sales of only red products, which approach is better suited? 1.SUMX and FILTER. or. 2. CALCULATE and SUM. Thanks in advance. Best regards. Lucas. Solved! Go to Solution. 07-24-2020 07:31 AM.

2018年10月29日 · Both SUM() and SUMX() iterates through all the rows visible in the current filter context but SUMX() does so with more degrees of freedom so to speak. You can say that SUM ( tblName[ColName] ) is just Syntax Sugar for SUMX (tblName, tblName [ColName]) because only one column is involved.

The SUMX function in Power BI is a versatile DAX (Data Analysis Expressions) function that calculates the sum of an expression evaluated row by row over a table. Unlike the simpler SUM function, which works on a single column, SUMX allows for dynamic calculations by evaluating a formula or expression for each row and then summing up the results.
