looping through columns and perform rule engine

I would like to manipulate a lot of column in a table based on some conditions, and to avoid to do it one by one I tried to create a loop that executes a rule engine.
Unfortunately it doesn’t work how I expected and I don’t now how to proceed.
I upload a wf that - hopefully - demonstrates what I want to achieve, if you have any idea how to eliminate the rows that are not needed, I would really appreciate it.-

Hi @HarryKl

This should help you get in the right direction. It loops through all the columns from the main table instead and checks if there is a rule present in the rule book for set column and applies it accordingly.
