Row Filtering Question

Hi y’all,

I have a question about the following case! About my knowledge.

I am a Knime beginner.

I have already come a long way with a workflow but am now faced with a problem. The goal of my workflow is to display a price trend for certain products in a product group based on sales figures for a year.

To do this, I need to add a row filter, but I’m just not getting anywhere. The current table already shows the product, product group, month and year correctly.

Now I want to add a filter that only shows the products that were purchased in each month or at least in 9 out of 12 months.

How can I do this?

Thanks for any help!

René
