Error with Filtering Field Parameter by using Slicer

Hi VenkatesuReddy ,

Thank you for posting in Microsoft Community.

Create a Field parameter by new parameter in modeling pane where add all the columns from the Excel table after cleaning the headers into this Field Parameter.

Then create a supporting Table for systems which will let you filter based on "Product", "Category", etc.

In order to tell Power BI which fields belong to which system, create a mapping table for Field Parameter to System and join mapping table to Field parameter table. Now you can use a slicer to filter the table.
