How can I create dynamic parameters in Power BI using DAX?
 I’d like to understand how to make parameters responsive to user selections and how they can enhance interactivity in my reports. Any tips on practical examples or scenarios

Answer 1

Similarly, in Power BI, utilizing DAX, one can implement dynamic parameters by using measures and calculated tables that depend on user selections. To begin with, let's look at the procedure.

Create a Parameter Table: For Initial Creation, you may refer to the steps given and create a table that will store the possible parameter values. Modeling > New Table helps to create a table with DAX as follows:

ParameterTable = GENERATESERIES(1, 10, 1)

With this, a sequence of integers ranging from 1 to 10 will be generated, and these can then be employed as the values of your parameters. This can be modified to contain any set of values or range of values that you want.

Add a Slicer for the Parameter: After the table is created, work within it as in Slicer, enabling users to pick a value. In the Visualization Pane, click on Slicer and then on the ParameterTable column.

Utilize DAX to Generate Dynamic Measure: Previously, a measure was created indicating which parameter was chosen. For instance, if you wish to apply the increase on a sales number selected by the slider, a DAX measure would look like this:

SelectedParameter = SELECTEDVALUE(ParameterTable[Value], 1)

This will return the value selected in the Slicer. You can then use it in another measure for dynamic calculations.

AdjustedSales = SUM(Sales[SalesAmount]) * [SelectedParameter]

In this case, the AdjustedSales measure purposefully changes based on the user's selected parameter in the Slicer.

There are appropriate ways in Power BI to create dynamic parameters in DAX that modify calculations or other visuals depending on the user.

Answer 2

To develop DAX dynamic parameters in Power BI:

• Create a Table: Create a parameter table using DAX, for instance, ParameterTable = GENERATESERIES(1, 10, 1).
• Add a Slicer: Employ this table in a slicer to get the user input.
• Use a Measure: Create a measure such as SelectedValue = SELECTEDVALUE(ParameterTable[Value]) and use it in visuals or calculations.

This aids in making your reports more interactive and responsive to users' inputs.
