I have a flow which works when an item is marked as ordered with a tick box it sends the item to another list. I'd like it to first check if the line exists in the other list and amend and only create when it doesn't exist there. As we are finding alot of data is needing to be amended on the original list the flow is creating duplicate items which is starting to become troublesome.

Is there a flow that could do the check and update first?

Thanks Lorraine
