A very common case is when we want to check the state of a slicer, so that the selection made by the report user directly affects the result of a DAX formula. In our example, the selection in the Measure slicer defines the measure to display in the matrix. Depending on the selection on Options[Column] — which is displayed in the Measure slicer — the Selected Name measure returns the corresponding measure. The cost to evaluate Selected Name should correspond to the cost of evaluating only one of the possible measures Sales Amount , Total Cost , or Margin. This is what usually happens, but there are conditions where DAX is not able to correctly optimize the code.

In this article, we will delve into the intricacies of this powerful function and explore its role in data analysis and accurate projections. As the name suggests, it allows you to define multiple conditions and their corresponding outputs, similar to a switch statement in programming. With the SWITCH function, you can dynamically assign different values or perform specific calculations based on predetermined conditions. This level of flexibility makes it an ideal choice for forecasting purposes, where various scenarios need to be considered and different actions need to be taken based on those conditions. Unlike other functions that require nested IF statements, the SWITCH function allows you to define each condition and its corresponding output in a clear and concise manner. This not only simplifies the logic of your calculations but also improves the readability and maintainability of your Power BI reports. DAX is a formula language that enables you to create custom calculations and aggregations in Power BI. It provides a wide range of functions that help manipulate and transform your data to derive meaningful insights. These functions allow you to perform calculations on your data, such as summing up values, finding the average, counting the number of records, and determining the minimum and maximum values. Forecasting is an essential component of any data analysis project, and Power BI offers several powerful DAX functions to facilitate accurate predictions. The SWITCH function, in particular, shines when it comes to handling multiple conditions and producing tailored outcomes.

Data type is text, if I change it to numbers I just get an error for everything, with a message saying Cannot convert value 'Expired' of type Text to type Integer. Microsoft Fabric Partner Switch statement power bi Engage with the Fabric engineering team, hear of product updates, business opportunities, and resources in the Fabric Partner Community.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Evaluates an expression against a list of values and returns one of multiple possible result expressions. This function can be used to avoid having multiple nested IF statements. The following example creates a calculated column of month names:. This is accomplished by setting expression to TRUE, as shown in the following example, which compares Reorder Point and Safety Stock Level on products to identify potential risks of running out of stock:. The order of values matters. In the following example, the second result is never returned because the first value is less restrictive than the second.

Conditional expressions are one of the most commonly used expressions in any language as well as DAX. If you ever need to write multiple IF statements in DAX, then you know that it makes the expressions hard to read. Here is an example of an expression with one IF statement:. The expression above returns Green as the background color if the EnglishEducation is Bachelors, otherwise, White, here it is used as the conditional formatting:. This is only for three of those values, you can imagine how the expression would be if we have five values, or what if we have even more! The Switch is a very simple and efficient function in DAX and many other languages to help writing multiple IF statements much easier, Switch is written in this way:. Here is a method that works:. Replacing the expression with TRUE, and the value of that with a conditional expression means that you get the same output, but this time, you can write a condition that can be greater than, less than or even between values. The techniques above, especially the last one is what I use a lot in my expressions.

A scalar value coming from one of the Result expressions, if there was a match with Value, or from the Else expression, if there was no match with any Value. However, the argument can be an expression and the initial can be a constant. The following code:. This article describes how to optimize DAX expressions with mutually exclusive calculations that might cause slow query performance. This article describes how to apply conditional formatting on measures picked from a slicer and implemented using two techniques: field parameters and calculation groups. This article describes how to use the Group By Columns property to store the slicer selection by using the same column used in a SWITCH function to optimize the query performance.

Evaluates an expression against a list of values and returns one of multiple possible result expressions. Jared enjoys reading and spending time with his wife and three sons when he's not trying to make queries go faster. It provides a wide range of functions that help manipulate and transform your data to derive meaningful insights. Message 8 of It allows you to create custom columns or measures based on specific conditions. Mark my post as a solution! Example 3: Customer Satisfaction Level Analysis Suppose you are analyzing customer feedback for a retail chain. Waterfall charts are a powerful tool for visualizing changes in data over time. Hold on, this article might be more sci-fi than BI. By humans, for humans - Best rated articles:. Leverage Default Case: Always include a default case to handle unforeseen scenarios. Break down complex logic into multiple Switch statements if necessary. The use of this function is not recommended.

The lesson here is, be aware that there could be an additional cost for a SWITCH expression executed on a column that is crossfiltered by other columns and that is not directly filtered in the report. Explore quality Zebra BI content. However, the more important thing is that there are no additional storage engine requests for the Sales table. I needed to find something else. As the name suggests, it allows you to define multiple conditions and their corresponding outputs, similar to a switch statement in programming. Custom DAX functions can be reused across multiple reports and dashboards, saving you time and effort in the long run. Keep in mind that the data types in all result and else arguments must be the same. How can we integrate these two functions? The Selected Name measure provides the optimal execution. Which one of these functions should you use? This browser is no longer supported. If there are no matching values the Else value is returned. Top Solution Authors.
