I have a scheduled workflow that runs every 30 minutes. This is based on a saved search showing a list of items included in new invoices created. Is it possible to criteria in a saved search to say show only the ones created in the past hour? Also, for the 30-minute interval, is it executed like at 5:30pm, 6pm, 6:30pm, etc. Regardless when I created the workflow? So if I created the WF at 5:45pm, will it be triggered at 6pm or 6:15pm?

The workflow runs on a backend scheduler. It is on the hour and half hour (6:00, 6:30, 7:00 etc)

Got it. Thank you.
