Introduction: In Power BI, making decisions based on conditions is a common task encountered during data modeling and report creation. While the function provides a straightforward way to implement conditional logic, the function offers a more structured approach, particularly in scenarios involving multiple conditions. This article aims to compare and contrast the usage of nested statements and statements in Power BI, providing insights into their respective strengths and best practices through DAX code examples. IF SWITCH IF SWITCH Nested IF Statements: Nested statements are a simple yet effective way to handle conditional logic in Power BI. They allow you to evaluate multiple conditions sequentially, executing different actions based on the outcome of each condition. However, as the number of conditions increases, the readability and maintainability of nested statements may diminish. IF IF Result =
IF ( Condition1, Value1,
    IF ( Condition2, Value2,
        IF ( Condition3, Value3,
            Default_Value
        )
    )
) SWITCH Statements: The function offers a more structured alternative to nested statements, especially in scenarios involving multiple conditions. It evaluates a single expression against a series of values and returns a corresponding result for the first matching value. This results in cleaner and more concise code, enhancing readability and maintainability. SWITCH IF Result =
SWITCH (
    Expression,
    Value1, Result1,
    Value2, Result2,
    Value3, Result3,
    Default_Result
) Comparative Analysis: While nested statements are straightforward for simple conditions, but they can become cumbersome and difficult to read as the number of conditions increases. On the other hand, statements offer a more structured and readable approach, especially for complex scenarios involving multiple conditions. Readability: IF SWITCH As the number of conditions grows, nested statements require additional nesting, leading to longer and more convoluted code. statements, however, remain concise and scalable, making them a preferred choice for handling a large number of conditions. Scalability: IF SWITCH Both nested statements and statements have comparable performance in Power BI. However, statements may offer slight performance improvements in scenarios involving a large number of conditions, as they evaluate each condition only once.
