Are there example workflows for the solution of such problems?

In Power Bi it is very easy, but I would like to convert this to Knime, because I need the table here to match later…
Thnx and Greetings!
Hi there @Jana11,
welcome to KNIME Community!
Have checked link but not sure what is your desired output at the end. If you share sample of your input data and expected output someone might give it a try to create example or give suggestions…
Regarding workflow examples you can always check KNIME Hub
