October update has TopN functionality but it is not upto the mark. Like how user can drag and drop the field / measure for TopN filter. If user clear the filter then dragged field disappear, user can not add again measure again in filter section. Could you please help me out here.
I agree with you. I think it is better to use a dropdown box for the value selection in this scenario as Sean mentioned above. Could you also submit this request on Power BI Ideas? So that we can vote it up, and Power BI team will take good consideration about it and make this feature come sooner.
@Shubham Are you talking about end users in the Service?
As a report author in the Desktop you have all the functionality to add/remove the filter settings. If you are talking about end users in the Service interacting with the report then I would consider that "by design"... I'm creating a visual on TopN based on the criteria I want the end user to use. The fact that they can interact with Filters doesn't mean I want them saving or modifying the report. If you want to do that, share via a Content Pack or give them access to the dataset to build their own.
If they removed the filter, they can navigate back to the dashboard and into the report again and it should reset to the original filter set.
