Hi @Softbear,
I tried it and it worked for me. I used the Common Data Service Trigger to track against my Business Process Flow (Change Request Process) and limit it to running only when the status code changes. Then I evaluated the status code label to make sure it is set to Finished. Thanks for asking this question, it gave me an idea for another issue I was trying to solve.
I hope this helps you out!
