I am trying to copy a list of survey responses that I have extracted, so as to keep a copy before modifying the list.
I have found if I duplicate the lists then they seem to mirror each other, i.e. if I delete from one list then it also deletes from the other.
The only common thing I can see between the lists is the targeting workflow id
If I read in the list in a new workflow and save it to a new list then they do not have this behaviour.
Am I misunderstanding the way lists work?
Correct. No two lists should target the same workflow ID directly because they override each other.
However, you can always use something like Enrichment: How to configure enrichment activities in Adobe Campaign Classic
Hope this helps!
All the best,
