Here is the documentation on this topic:
Scheduling in SAS
You can certainly use your existing scheduling system instead of those available in SAS. The options available through SAS Management Console let SAS users / administrators schedule flows within the SAS environment rather than using a separate system, build the individual job commands based on options set in SAS Management Console's schedule manager and using the application server context's Batch Server which applies the options for that context and environment, like a connection to the Metadata Server. Depending on the scheduling server being used the flows can be triggered by time or file events, and in the case of grid schedulers the jobs are submitted as grid jobs so could execute on any node in the grid or have additional grid options applied.
