The following warning might occur when executing SAS^® Stored Processes:

This warning occurs if the STPSRV_HEADER function is specified in a SAS Stored Process that is NOT registered to produce streaming results. This includes SAS Stored Processes registered to execute on a SAS Workspace server, which cannot produce streaming results, as well as SAS Stored Processes registered to execute on a SAS^® Stored Process server, which can also produce transient and permanent package results or no results in addition to streaming results.

The STPSRV_HEADER function is designed to allow you to add to or modify the HTTP header that is generated for Web–based output.

To avoid the warning and to work properly, a SAS Stored Process that uses the STPSRV_HEADER function must:

1. Execute on a SAS Stored Process server
2. Produce streaming results
3. Execute in a Web client.

For more information on the STPSRV_HEADER function, see the SAS(R) 9.3 Stored Processes: Developer's Guide.

See SAS Note 44058, " 'WARNING: No logical assign for filename _WEBOUT' occurs," for another scenario that results in this WARNING message.
