Never tried this one. I'll run a test when I have 5 minutes
Try leaving the Due In field empty instead of using a value of 0. We create completed activity records this way all the time and that's the only difference I see between your flow step and ours. The 0 may be overriding the status because it's calculating a due date of today.
Hi David Lyons,
Thanks for the suggestion. I tried leaving it blank and it automatically gives it a 5 day due date. I will chase up with our CRM admin encase this is a default setting he has applied on the SFDC side.
