Dax Function: AND
Category: Logical Functions
The AND function in Power BI is a DAX logical function that evaluates two conditions (expressions) and returns TRUE if both conditions are true; otherwise, it returns FALSE. It is commonly used for conditional logic in calculated columns, measures, and filters.
Purpose:
The AND function is designed to combine two logical tests and return a single Boolean result. It simplifies complex conditional statements by handling multiple conditions simultaneously.
Type of Calculations:
- Logical evaluations based on multiple conditions.
- Decision-making logic for data filtering or calculations.
Practical Use Cases:
- Filtering Data: Display data only when two conditions are met (e.g., sales > 1000 and region = “West”).
- Dynamic Calculations: Perform calculations based on compound criteria.
- Conditional Formatting: Apply formatting when multiple conditions hold true.
AND(<logical1>, <logical2>)
| Parameter | Type | Description |
|---|---|---|
logical1 | Boolean | The first condition to evaluate. Must return TRUE or FALSE. |
logical2 | Boolean | The second condition to evaluate. Must return TRUE or FALSE. |
How Does AND Dax Function Works?
The AND function operates on two logical tests. If both tests evaluate to
Result = logical1 ∧ logical2TRUE, the function returnsTRUE. Otherwise, it returnsFALSE. Mathematically, this follows the logic of:Where ∧ represents the logical “AND” operator.
What Does It Return?
The AND function returns a Boolean value:
TRUEif bothlogical1andlogical2are true.FALSEotherwise.
When Should We Use It?
- Multi-Condition Filters: Apply filters where two criteria must both be met.
- Validations: Check multiple rules before applying transformations or calculations.
- Dynamic Measures: Create measures that only calculate under specific combined conditions.
Examples
Basic Usage
Evaluate if both sales and profits exceed 100:
Result = AND(Sales[SalesAmount] > 100, Sales[Profit] > 100)
Result: Returns TRUE only when both conditions are true.
Column Usage:
Add a column to determine if sales are high and within a specific region:
HighSalesInRegion = AND(Sales[SalesAmount] > 5000, Sales[Region] = "North")
Result: Displays TRUE for rows meeting both conditions.
Advanced Usage
Combine AND with IF for conditional measures:
HighValueCustomer = IF(AND(Customer[PurchaseCount] > 10, Customer[LifetimeValue] > 10000), "Yes", "No")
Result: Categorizes customers based on purchase count and lifetime value.
Tips and Tricks
- Use with Related Functions: Combine with OR for complex logical conditions:
ComplexCondition = OR(AND(Sales[SalesAmount] > 500, Sales[Profit] > 50), Sales[Region] = "East") - Alternative Syntax: For more than two conditions, use
&&as an alternative to AND:Result = Sales[SalesAmount] > 500 && Sales[Profit] > 50 && Sales[Region] = "East" - Avoid Nested ANDs: If you have more than two conditions, using
&&can improve readability and performance.
Performance Impact of AND DAX Function:
- Efficient for small datasets but may impact performance when used with complex expressions or large tables.
- Combining multiple AND conditions in calculated columns may increase model processing time.
Related Functions You Might Need
- OR: Evaluates multiple conditions and returns
TRUEif any are true. - IF: Implements conditional logic based on a single or compound condition.
- NOT: Reverses the result of a Boolean expression.

The AND function evaluates two conditions and returns TRUE only if both are true.
No, the AND function is limited to two parameters. Use && for more conditions.
The AND function requires all conditions to be true, while OR returns TRUE if any condition is true.
No, both achieve the same result, but && is often preferred for readability in complex conditions.
Yes, AND is widely used in both measures and calculated columns for logical evaluations.
