Two ways to trigger an Action

On a schedule
Select On a schedule when you want the Action to run at a fixed time — daily, on specific weekdays, or one day each month. Chief runs the prompt at that time regardless of whether anything changed in the Project. This is the right choice for standing reports and digests: “every Monday at 8 AM,” “the 1st of each month.”Whenever there is new source data
Select Whenever there is new source data when you want the Action to react to files being added, rather than to the clock. When you pick this, a Trigger Options box appears with two choices:- Run only on the new asset — the run processes just the file that was added.
- Run on all matching assets — the run re-processes everything in scope each time new data arrives.
ℹ️ Good to know: A new-data Action only fires when data is actually added. If nothing new arrives, there is no run — that is expected, not an error.
FAQ
Can I switch a trigger type after creating the Action?
Can I switch a trigger type after creating the Action?
Yes. Open the Action’s editor, change the Trigger Type radio, set the new options, and save.
My new-data Action hasn't run in days — is it broken?
My new-data Action hasn't run in days — is it broken?
Probably not. A new-data trigger only runs when new source data is added to the Project. If no files have been added, there is nothing to trigger it. Check the Project for recent uploads, and confirm the Action is not paused.
“Run only on the new asset” looks at just the file that arrived; “Run on all matching assets” re-runs against the full scope each time. Use the first for per-file alerts and the second when each new file should refresh a whole summary.
