I use it in almost every query I write.

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.

I have a calculated column in my table that works out number of Days to Expiry, and I then need another calculated column to allocate descriptors based on that number to give me 'Expiry Status'. I am trying the following:. Go to Solution. View solution in original post. I tried this, but it gives a result of 'Expired' for every line of data, although there are definitely some that should be in each category. Any idea what I am doing wrong? 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. Thanks so much for getting back to me. But it is still not working, giving me an incorrect syntax error. Can you spot what I have done wrong? Many thanks in advance!

However, if you need to check multiple conditions, things get complicated. Custom DAX functions can be reused across multiple reports and dashboards, saving you time and effort in the long run.

Posted by Errin O'Connor on Nov, 21, Power BI is packed with useful features, and one of them is the Switch function. Think of the Switch function as your personal data assistant. The Switch function in Power BI is a logical tool that streamlines decision-making in data analysis. In simple terms, the Switch function looks at your data, checks certain rules you set, and then categorizes the data based on those rules. The structure of the Switch function is pivotal to its application.

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.

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 to be evaluated. Hi, Share the link from where i can download your PBI file. The first and most obvious alternative is the IF function. As a consequence, the Options[Index] column is directly filtered in the filter context and generates the optimal execution we previously described in this article. Power BI. This is what usually happens, but there are conditions where DAX is not able to correctly optimize the code. Less effort, more insights. As the world of data analysis evolves, so does Power BI. There must be a better way. The value1, value2, etc. Any idea what I am doing wrong? The Sales[Unit Cost] column is never referenced by the storage engine requests:.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.

Less effort, more insights. Returns different results depending on the value of an expression. However, this is the result of two filters on the same Options[Name] column applied to the matrix visual: one from the page filter and one from the slicer. Message 11 of The Switch function in Power BI is a logical tool that streamlines decision-making in data analysis. Message 6 of The fear of missing out is intense. By mastering these advanced techniques, you will be able to create highly accurate and reliable forecasts. Using different data types can lead to errors. All forum topics Previous Topic Next Topic.
