In reply to Hugh Shinn.

Hugh, there are a number of possible reasons that you see that message. For each code submission, you have two SAS environments in play: the SASApp workspace server, and a SAS grid node session. So it's important to understand where the code is running, as the options, user identity, and operating environment can affect how OS commands/shell access is processed.

It's possible that your FILENAME PIPE is referencing a resource that you (the account running the job) really does not have access to.

I suggest that you work with SAS tech support to determine the root cause for the error.
