What is Power BI SELECTEDVALUE?

Definition: Power BI SELECTEDVALUE is a DAX function like Format Dax that extracts a single value from a column within a specified context. This retrieval is based on the prevailing context or filter conditions. The SELECTEDVALUE function is useful in situations where there is an expectation of only one possible value. It helps avoid errors that arise from multiple or no values.

By leveraging DAX SELECTEDVALUE, you can enhance your data analysis and visualization within Power BI. It simplifies the process of obtaining a specific data point within a given context. Thus, it streamlines calculations and contributes to the overall efficiency of data-driven decision-making. This SELECTEDVALUE in Power BI also proves valuable in creating dynamic and interactive reports. This provides users with a more seamless and tailored experience.

Here is the syntax of the SELECTEDVALUE function in Power BI:

SELECTEDVALUE ( <ColumnName>, [AlternateResult] )

• ColumnName: The name of the column you want to check.
• AlternateResult (optional): The value you want to return if no selection is made or if multiple values are chosen.

Why is the Power BI SELECTEDVALUE Useful?

The Power BI DAX SELECTEDVALUE function plays a pivotal role, offering nuanced data retrieval capabilities. When integrated with a connector in Power BI, this function’s advantages become even more pronounced, positioning it as an indispensable asset in your data analysis toolkit. Let’s explore the multifaceted benefits that make the SELECTEDVALUE function a key component of effective data management.

• Single-value retrieval: At its core, SELECTEDVALUE excels in precision. It allows you to extract a singular value from a designated column. This focused approach aids in zeroing in on specific data points critical to the analytical context.
• Context-awareness: One of SELECTEDVALUE’s standout features is its context-aware nature. It adapts dynamically to prevailing filtering conditions, ensuring the output remains relevant and responsive across diverse analytical scenarios.
• Error handling: The SELECTEDVALUE demonstrates its prowess in error handling by addressing scenarios with multiple or zero values. This capability contributes significantly to maintaining data integrity and preventing calculation discrepancies.
• Dynamic calculations: SELECTEDVALUE’s responsiveness to changes in context or filters adds a layer of dynamism to calculations. This adaptability enhances the flexibility of data analysis, allowing for real-time adjustments based on contextual shifts.
• Enhanced readability: Integrating SELECTEDVALUE into measures and calculated columns improves code readability. This simplifies expressions and aids users and developers in understanding and navigating the logic seamlessly.
• Conditional logic: The seamless integration of SELECTEDVALUE into conditional logic empowers creating logic based on the singular value it retrieves. This proves invaluable in constructing responsive and context-driven reports.
• User-friendly: In the hands of report designers and business analysts, SELECTEDVALUE brings a user-friendly dimension to Power BI. Its application facilitates effortless navigation and analysis, contributing to an intuitive and interactive reporting experience.

How to Implement Power BI SELECTEDVALUE for Enhanced Data Evaluation?

The following example shows what “filtered down to one distinct value only” means. We’ll use the following data table named MarketShareAnalysis.

Using this table, create a measure named MarketShareMeasure

MarketShare_Measure = SELECTEDVALUE(MarketShareAnalysis[MarketShare], “Not Distinct Value”)

To understand how it works, let’s utilize a Table visual and slicer in Power BI for value filtering. In the image below, the table displays the alternate value “Not Distinct Value” in the “Market_Measure” column. This occurs because the table visual employs a single column, “Vendor”, with multiple values for different quarters. This leads to the display of an “alternate value”.

Now, we use or drop the “Quarters” column in the table visual to make it a distinct value. It becomes evident that every row is unique, and the values are prominently displayed in the measure column. It’s important to observe that the Total row exhibits alternating values. This occurs because the total row takes into account multiple rows, not just a singular one.

Now, we employ the slicer to filter by quarter and vendor, like Q1 and Apple. This results in a single unique record display after applying the filter. That’s why the row shows a numeric value instead of the alternate total value.
