One filter for multiple workflows

Hello! I’m brand new to KNIME, however I did try searching extensively and couldn’t find an answer to this question. Is it possible to set up ONE rule-based filter to affect all/multiple workflows in a project?

I am using KNIME to take the data from several reports and generate data for multiple import templates. These are being run over and over again for each sprint of clients. Each run I only need a certain group of clients, and right now I have a rule-based filter on every workflow filtering out the same clients. I have to update every filter node every time we switch groups of clients.

What I would LIKE to do is have one single filter that I can update each run with the clients I need, and have that filter all of my workflows. Is there any way to accomplish this?

Hi @bradhorn,

welcome to the Knime Community. About your question, yes, that is absolutely possible using the Call Workflow Nodes. As follows those I use in that example but check the others as well!

Process

  1. You start creating your workflow which contains the desired filter functionality and, after verifying it’s functionality with test date, you add the Container Input as well as Output Node


  2. Then you connect your workflow in question like so

  3. You execute the node from step #2

I hope this helps, in case you need more support, I kindly ask for an example workflow and sample data to create a solution for you.

Best
Mike
