flow variable to exclude column via column filter

Dear all,
I managed to use a string collection flow variable together with a column filter node and the option Enforce inclusion to set the columns to include, however I tried the opposite: setting the flow variable to set the column to exclude, with the enforce exclusion but it does not seem to work.

This was originally proposed in this related discussion

Here is an example workflow demonstrating a branch for inclusion and exclusion.

Hello @l.thomas,

follow same approach as for Column Filter where you use flow variable to control included columns. Add all columns to excluded list and check Enforce exclusion.



I see ! I was missing that bit:

thanks a lot !
