Power Query allows the use of Dynamic M parameters in multi-select scenarios. This functionality can prove helpful while designing dynamic user interfaces in Power BI as it enables users to make multiple fltering selections. For instance, if you are creating a Power BI report that allows users to select multiple countries to filter data, Dynamic M parameters can be utilized. The process begins by creating a new parameter labelled as 'SelectedCountries' of 'Text' type in Power Query editor.
The parameter is then used in your query. Suppose you have a 'Sales' table with a 'Country' column. Filtering the rows of the 'Sales' table as per the countries selected by the user can be achieved by incorporating the newly created parameter.
Dynamic M parameters enhance the functionality and usability of Power BI reports by allowing multiple select options. This feature is extremely powerful and flexible, leading to a more interactive user experience. It involves expressing complex user prompts in the query to filter the data based on user selection. This results in a more dynamic and customizable data analysis experience in Power BI.
Power Query Dynamic M Parameters are a powerful tool for creating dynamic user interfaces in Power BI. They can be used to allow users to filter data by making multiple selections from a slicer. To use Dynamic M Parameters, first create a new parameter in the Power Query editor and name it. For example, if you want to filter data by country, you might name the parameter SelectedCountries and choose Text as its type. Next, use the parameter in your query. For example, if you have a Sales table with a Country column, you can filter the rows of the Sales table based on the countries selected by the user. To do this, add a filter step to the query, and use the parameter as the filter condition. This will enable the user to select multiple countries and filter the data accordingly. Additionally, you can add a “Select All” option in the slicer to make it easier for the user to select all countries. Finally, when the report is published, the slicer will filter the data based on the user’s selections. This will enable the user to make multiple selections and dynamically filter the data accordingly.
