To the remarks made by user24feb:
- Pretty good post from SAS User Groups 
- You have some more options for scheduling, and the one that fits better in your needs, it is something for you to decide:
- SAS Grid Manager : pretty expensive license, but includes Platform Computing for Scheduling (with its beautiful functionalities) and will add you nice features like parallel processing, load balanding, high availability and improved scheduling.
- You can use your own Enterprise Scheduler: it will require from you to do some manual work, but it has some good advantages, like the possibility to integrate your SAS processes with other processes within your Enterprise flows.
