SUM DAX Function (Aggregation)
Adds all the numbers in a column.
Syntax
| Parameter | Attributes | Description |
|---|---|---|
| ColumnName |
The column that contains the numbers to sum. |
Return values
Result of the sum.
Remarks
When used with a single column, the SUM function internally executes SUMX, without any performance difference.
The following SUM call:
SUM ( table[column] )
corresponds to the following SUMX call:
SUMX (
table,
table[column]
)
The result is blank in case there are no rows in the table with a non-blank value.

Examples
-- SUM is the short version of SUMX, when used with one column only
-- SUMX is required to evaluate formulas, instead of columns
DEFINE
MEASURE Sales[# Quantity 1] = SUM ( Sales[Quantity] )
MEASURE Sales[# Quantity 2] = SUMX ( Sales, Sales[Quantity] )
MEASURE Sales[Sales Amount] =
SUMX ( Sales, Sales[Quantity] * Sales[Net Price] )
