Hi community,

I am wondering how this two options work.

Is there a difference in the output of these two options if the Action Name field is "Add pending worker" or "Move to HR"?

Because I have different output in two different environments: in the first one I have the option "Checklist manually allocated (...)" enabled and the journey is immediately allocated when a pw is created whereas with the option "When the action record becomes effective" the journey appears deferred in the date the pw will be created.

In the other environment I have the option "When the action record becomes effective" enabled and as before the journey is immediately allocated.
