I have setup a BE with a GI so when the appointment closed status, it will email a notification. It is working fine if the appointment changes to Closed status. However, if after Closed, users Unclose it and Closed it again for multiple time and it will also trigger the BI multiple times. How do I make it to trigger only 1 time? I tried using Once for all records but it is not working. Can anyone explain how do we use Once for All records? and what is the difference with For Each Record? Thank you.
