OR DAX Function (Logical)
Returns TRUE if any of the arguments are TRUE, and returns FALSE if all arguments are FALSE.
Syntax
| Parameter | Attributes | Description |
|---|---|---|
| Logical1 |
The logical values you want to test. |
|
| Logical2 |
The logical values you want to test. |
Return values
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.
