Power BI Paginated Report have one parameter effect the available selections of another parameter

Hi, gblanks 

Based on your description, you want to create two parameters in a paged report and one of the parameters can influence the selection range of the other parameter, Cascading Parameters in a paged report meets your needs. You can define a set of related parameters so that the list of values for one parameter depends on the values selected in the other parameter. For example, the first parameter is independent and might display a list of product categories. When the user selects a category, the second parameter depends on the value of the first parameter. Its value will be updated using the list of subcategories in the selected category. When the user views the report, the values of both the category and subcategory parameters are used to filter the report data. Please refer to the official documentation for details on how to do this.
