OR DAX Function (Logical)

Returns TRUE if any of the arguments are TRUE, and returns FALSE if all arguments are FALSE.

Syntax

OR ( <Logical1>, <Logical2> )
Parameter Attributes Description
Logical1

The logical values you want to test.

Logical2

The logical values you want to test.

Return values

Scalar A single boolean value.

The value is TRUE if any of the two arguments is TRUE; the value is FALSE if both the arguments are FALSE.

Remarks

The OR function accepts only two arguments. Consider using the operator || to avoid multiple nested calls in case there are three or more conditions to evaluate in a logical OR.
