Enter the following DAX expression into the DAX formula bar, and then press Enter: Sales Amount = SUM(Sales) In the Data pane, expand and right-click Sales measures, and then select New measure. Name the table Sales measures, and then click Load. In the Create Table dialog, leave the values blank. Cross filter direction: Single (‘Yearly Average Exchange Rate’ filters ‘Date’)Ī measure group helps you organize different measures by having them in a single table.Instead, create a relationship between Yearly Average Exchange Rates and Date on the Year column. This relationship, however, isn't correct for our model. If you have Autodetect for relationships on, a relationship between Country Currency Format Strings and Sales territory on the Country column may have been created. Table 2: Country Currency Format Strings.If you have Autodetect for relationships on, the relationship between Country Currency Format Strings and Yearly Average Exchange Rates on the Country column may have been created for you. Relationships are needed between your new Yearly Average Exchange Rates and Country Currency Format Strings tables, and between Yearly Average Exchange Rates table and the existing Date table. ![]() In the DAX formula bar, enter the following expression: Year = YEAR(), and then press Enter. In Model view, right-click the Date table, and then select New column. Table name: Yearly Average Exchange Rates CountryĪ new Year column is needed in the existing Date table. Repeat the previous steps for the following table: Verify the table looks correct, and then click Load. Table name: Country Currency Format Strings Country In the Create Table dialog, enter the following table name, and then copy and paste the following table: To get started, you first need to add two tables. The sample model doesn't contain all the data necessary to create and use dynamic format strings. After downloading, open the file in Power BI Desktop. By using the sample model, you can add currency conversion to show converted sales amount by year. You can do just that with the sample Adventure Works 2020 PBIX file available at DAX sample model. The best way to learn about a new feature is to try it yourself. If you want to go back to using a dynamic format string again, you must reenter the DAX expression. Because there's no undo to this action, a dialog appears asking if you want to proceed. To delete the dynamic format string and return to using a static format string, in the Formatting section > Format listbox, select a different format option. ![]() Verify your dynamic format string works in a visual. For example, the following expression looks up the currency format string we want from a ‘Country Currency Format Strings’ table: Overwrite the string with a DAX expression that outputs the correct format string for your measure. Whatever the static format string was in use before switching to Dynamic is prepopulated as a string in the DAX formula bar. This drop down is how you can switch between the static measure DAX expression and the dynamic format string DAX expression. A new listbox with Format already selected appears to the left of the DAX formula bar. In the Measure tools ribbon > Formatting section > Format listbox, select Dynamic. In the Data pane, select the measure for which you want to specify a dynamic format string. Create dynamic format strings To create a dynamic format string ![]() To learn more, see Calculation groups - Dynamic format strings. The same DAX patterns that work with calculation groups can also be utilized in dynamic format strings for measures, but the scope is limited to individual measures instead of all measures in the model. This applies different format strings to the measure depending on the context.ĭynamic format strings can also be used with calculation groups. When using dynamic format strings, the measure keeps its data type and isn't forced to change to a string data type. That is, with FORMAT even numeric data types are returned as a string, which may not work with visuals that require numeric values, like charts. When in Preview, functionality and documentation are likely to change.ĭynamic format strings overcome an inherent disadvantage of using the FORMAT function. Dynamic format strings for measures is currently in Preview.
