Dax Function: FALSE
Category: Logical Functions
The FALSE function in Power BI is a DAX function that returns the logical value FALSE. It is commonly used in logical expressions, comparisons, and conditional calculations to represent a Boolean value explicitly.
Purpose:
- Provides a simple way to define a
FALSEBoolean value. - Used in logical expressions and conditional statements for decision-making processes.
Type of Calculations:
- Returns a static Boolean value
FALSE. - Used in conjunction with logical operators (e.g.,
AND,OR) or conditional functions (IF,SWITCH).
Practical Use Cases:
- Default Logic: Assign default
FALSEvalues in calculated columns or measures. - Conditional Logic: Evaluate conditions where
FALSEis a required outcome. - Data Validation: Represent a failed check or condition explicitly.
FALSE()
Parameters
The FALSE function does not take any parameters.
How Does FALSE Dax Function Works?
The FALSE function is straightforward. It represents a Boolean FALSE value and is used in logical operations or as a standalone value. In DAX, FALSE is equivalent to 0 in numeric contexts or when evaluated in comparisons.
Example:
- Logical comparison:
IF(Sales[Discount] > 0, TRUE(), FALSE()) - In this case, if the discount is not greater than 0, the
FALSE()function explicitly represents the result.
What Does It Return?
The function returns a Boolean value of FALSE.
When Should We Use It?
- Logical Comparisons: Use in conditions where
FALSEmust be explicitly defined. - Default Assignments: Set a default Boolean value in calculated fields or measures.
- Testing Scenarios: Validate that logical expressions evaluate to
FALSE.
Examples
Basic Usage
Explicitly return FALSE:
Result = FALSE()
Output: The result is always FALSE.
Column Usage:
Use FALSE in a calculated column for default logic:
Is Discounted = IF(Sales[Discount] > 0, TRUE(), FALSE())
Explanation: Assigns FALSE for rows where there is no discount.
Advanced Usage
Combine FALSE with other logical functions:
Promotion Status = IF(AND(Sales[Revenue] > 1000, Sales[Profit] > 200), TRUE(), FALSE())
Explanation: Returns TRUE only if both conditions are met; otherwise, it returns FALSE.
Tips and Tricks
- Boolean Clarity: Use
FALSEinstead of 0 for better readability in logical expressions. - Avoid Redundancy: When possible, simplify logical expressions to avoid unnecessary use of
FALSE(). - Combining with Logical Functions: Pair with
TRUE(),NOT(), orISBLANK()for advanced logical operations.
Performance Impact of FALSE DAX Function:
- Efficient Execution: Since
FALSEis a static value, it does not introduce additional computational overhead. - Boolean Context: It performs optimally in logical expressions and conditions.

TRUEif all conditions are true; otherwise,FALSE. - OR(): Returns
TRUEif at least one condition is true; otherwise,FALSE.
