Bulk create when entry doesn't exist

Hi there,

I have a little workflow that creates a weekly order based on the user’s subscription.
The workflow should create an order for every user that has an active subscription. However, I only want it to create an order when the combination “week” and “user” does not exist.

I figured it should be taken care of in the “only when” field down at the bottom. But I have no clue on how to correctly implement this. Hope anyone can help me out here :slight_smile:
Thanks!test
