How to filter a KNIME Data App table by the latest date?

Date Filter Data App.knwf

wellness_dummy.csv

Hi everyone,

I’m new to KNIME Data Apps and I’m struggling with something that seems simple: I want the Data App to show only the rows from the most recent date in my dataset.

My table has a column Date_ddmmyyyy (string like

12/08/2025

).

What I want to achieve:

*

Automatically detect the latest date in the data

*

Filter the table so the Data App shows only those rows

*

Later allow the user to pick another date with a widget

I tried using a Date&Time Widget + flow variables connected to a Row Filter, but I can’t get it to work, and I couldn’t find a similar example in the forum.

I’ve attached a small workflow and a sample CSV.

Any advice or a simple example of how to filter by the “latest date” would really help. Thank you very much!
