My User Event script is not triggering when I am creating intercompany sales order. I have deployed the script on sales order and made it available for all roles. Is there something else we need to setup?

maybe obvious ones but check: - DEPLOYED checkbox is actually checked - Status is released - INACTIVE is unchecked also why isn't it triggering? are you trying to catch in debugger and not seeing it, or is your expected behaviour not working? if debugging make sure you're owner and status is set to testing. otherwise to confirm it's running, try log.debug and ensure log level in deployment is set to Debug.
