I have a RSVP tool created with forms and workflows. The end user can create an event and sessions, each session as a attendee limit. When someone RSVP to the session the workflow will first check if there is still room, if no send full email, if yes it will +1 to the attendees number, add the user, ex..
I ran into and issue where if the session is 9/10 attendees and 2+ people click within a few seconds/minutes of each other it will add all 2+ becuase all the workflows are running at the same time.
Is there a way to tell a workflow to only run 1 run at a time, set a queue?
