I wasn't aware of this "Update Service" node. Nice find! Is this a recent addition?
I had a little look at it, but was getting some strange results. When you hover over the "Assess BPM" information, it implies that the original process will get cancelled when this is set to yes, but this doesn't seem to be the case? (Just to confirm, I switched it to a different CI within the same service).
On my first attempt, I ended up having two background processes running on one request in parallel, which I assume is not intended and could very well cause some big issues?
Interested to know what the recommended way of using this would look like. I'm assuming you want to follow it with an "End process" node? But like I said, I was originally expecting it to cancel the original process regardless of what followed based on the information shown when you hover over "Assess BPM".
