Value Filter Behavior (Preview)
Posted: Wed Jan 08, 2025 3:37 am
These new features make it easier to document and maintain your semantic model, ensuring that it is always up to date with the latest changes.
DAX, the formula language used in Power BI, has an automatic filtering mechanism informally known as “autoexistence.” This mechanism is triggered when multiple columns in the same table are filtered. DAX understands that not all combinations of values in these columns are valid and therefore automatically excludes invalid combinations. This process generates a merged value filter that not only returns valid combinations but also affects the measured calculations.
With the latest updates to Power BI, you now have qatar whatsapp resource more control over this behavior in your semantic model. You can decide whether to disable merged value filters and enable independent value filters instead. By setting the “Value filter behavior” option to Independent, filters from the same table will be kept separate instead of being combined by the DAX engine.
Understanding the behavior of the current value filter.
When filtering multiple columns from the same table, the current default behavior combines these filters into one, considering only existing combinations. For example, if you have a “Year” column with values like “2023” and a “Month” column with values like “January 2024,” filtering on both columns will only consider valid combinations. The combination of the month January 2024 with the year 2023 does not exist and therefore would not be included in the filter. However, there are situations where the results can be surprising.
Influence the behavior of the value filter.
This month, we introduced the option to control this behavior in your semantic model using the “Value Filter Behavior” setting in the model view properties panel. There are three options available:
