Yes, there is. With the term used, LPAR, you mean IBM mainframe (z/OS MVS) system, possibly TSO (interactive) or a batch job, as it goes.
There is a software product called ThruPut Manager
http://mvssol.com/ that provides this capability, directing batch jobs based on flexible user-defined criteria. Another similar product is called OS/EM.
Native with z/OS and WLM, you can implement SCHDENV, or you can require a user code a /*JOBPARM with SYSAFF= to direct the batch job to an appropriate LPAR.
Lastly, one technical prevention mechanism to disallow execution on any non-authorized LPAR, you can have your SAS admin only define the SAS datasets in the master catalog for the LPAR where SAS is authorized. If a job is accidentally started on an unauthorized LPAR, the job will get a JCL ERROR because the SAS system libraries are not found.
