Hi AmarishJayanth 

Thanks for reaching out to the Microsoft fabric community forum.

you can create a parameter in power query, then set the parameter with slicer, you can refer to the following link.

Dynamic M query parameters in Power BI Desktop - Power BI | Microsoft Learn

The following sample cannot allow the user to input the parameter, if you want to edit the parameter to change the filter, you can only do it in power query or edit it in data source setting when the report is published to Service, you can refer to the following link.

Sample data 

Step1: Create a parameter in power query

Step 2: Modify the ODATA Service URL:

Open Power Query Editor by navigating to the "Home" tab and clicking on "Transform Data".
Locate the query which retrieves data from the ODATA service.
In the query, replace the static date in the ODATA service URL with the parameter you create. For example:

let

    Source = OData.Feed("https://your-odata-service-url?date=" & Date.ToText(SelectedDate, "yyyy-MM-dd"))

in

    Source

Step3: Load the Data

• Close and apply the changes in the Power Query Editor.

• The data will now be filtered based on the selected date in the slicer.
