It is not currently possible to make the Run As option available to non-Administrators.
"To run the job under credentials other than your own, select Run As from the pop-up menu. This option is available only if you are logged on as a SAS administrator."

The SAS Users Group for Administrators (SUGA) is open to all SAS administrators and architects who install, update, manage or maintain a SAS deployment.
