The following error might occur when attempting to read from or write to a network path in a stored process:

ERROR: Undetermined I/O failure.

This error typically occurs when the account that is executing the stored process does not have the necessary Read or Write access to the specified network path. In general, the following guidelines apply:

• If you execute your stored processes on a SAS^® Stored Process Server, then the sassrv account (or the login account for SAS General Servers) must have the appropriate Read or Write access to the files and the directory paths that you want to allocate in stored process code.
• If you execute your stored processes on a workspace server, then the connecting user ID must have the appropriate Read or Write access to the files and the directory paths that you want to allocate in stored process code.

The basic differences between the SAS Workspace and the SAS Stored Process servers are outlined in SAS Note 31155, "Differences between using a SAS Workspace Server and SAS^® Stored Process Server for executing stored processes in a BI environment".
