The following messages might occur when running a SAS program that uses the %STPBEGIN and %STPEND autocall macros:

ERROR: No logical assign for filename _WEBOUT.  
WARNING: No body file. HTML output will not be created.   

These messages can occur if the SAS program is not being executed as a stored process.

Using the %STPBEGIN and %STPEND macros is only valid when you are executing code through a SAS^® Stored Process Server or SAS^® Workspace Server, so these macros will not work from a regular SAS session in batch mode or through the Display Manager. You must first register the stored process from the SAS^® Management Console or from SAS^® Enterprise Guide^®. Then you can execute the stored process from any of the BI clients such as SAS Enterprise Guide, the SAS^® Add-In for Microsoft Office, the SAS^® Information Delivery Portal, SAS^® Web Report Studio, and so on.

To test the code in a regular SAS session before you start using it as a stored process (which is always a good practice), you can comment out the %STPBEGIN and %STPEND statements and temporarily substitute ODS HTML statements. For example:

*ProcessBody;

/* %stpbegin; */

ods html file="<path>\myfile.html";
proc print data=sashelp.class;
run;

ods html close;
 
/* %stpend; */

For more information on using the %STPBEGIN and %STPEND macros, see the SAS 9.1.3 Integration Technologies, Developer's Guide.

See SAS Note 34120, "'ERROR: No logical assign for filename _WEBOUT' occurs," for another scenario that results in this ERROR message.

See SAS Note 33585, "'WARNING: No logical assign for filename _WEBOUT' occurs," for a scenario that results in a WARNING message about the _WEBOUT filename rather than an ERROR.
