Report parameters are a new Power BI Desktop feature that allows you to create dynamic slicers with which you can influence the appearance of the report.

Since recently, this option also exists in Power BI Desktop. In the “recipe” that follows, you will learn how to add and modify error bars on a column or bar chart.
Whether we use Excel BI or Power BI data model, we can create a hierarchy of employees manually or with the help of some DAX functions. In this text you will learn how to use two such functions: PATH and PATHITEM. With their help, it is possible to create calculated columns that show the hierarchical level of each of the employees within the company.
