I need to filter out some column, but the list of columns to keep can change, therefore I created a list that contains those and tried to use it in column filter-node as “included names” variable.
Unfortunately it doesn’t work.
I attached a workflow to show how I tried it.
Can you pls help me, why, and what would be the right name to do it ?
Thank you column filter from list.knwf (11.9 KB)
This is the right way to do it. Move your columns to the Exclude section and it will work as intended It basically needs values to be present to apply the flow variable to.
Note that you mention include names in your post but you applied it to exclude names. In any case, the usage of the flow variable (include names/exclude names) and in which section the columns are should match (include/exclude).
