Hello Angela,
Schedulers are available in most operating systems and you can schedule your Integration Toolkit (ITK) events using those.
For UNIX/Linux systems the scheduler is called "cron". Your system administrators can use this to execute the ITK scripts on a specific schedule.
For Windows the scheduler is called "Task Scheduler".
If you need further assistance configuring the ITK, please open up a Service Request on https://connect.ariba.com
Best regards
Fred
