FTP Outbound thread is not recording to SMAT file

The outbound thread is writing a file to the remote server, but not saving the outbound message in the outbound SMAT file that is set up in the thread.  The Save outbound messages option is checked and a SMAT file name is entered.

This thread is also using a (TPS Outbound Data) numfile.tcl proc that specifies a filename with a timestamp extension.  The resulting filename is different than the filename in the File parameter in the Fileset Options tab of the FTP Protocol Properties dialog.  Would that prevent the thread from recording the outbound message?

Is there another config option that I am missing, or should I include a tclproc in the Send OK Procs under the Outbound tab to force the write?  If so, how do I set the disposition or command to resolve this?

Thanks.
