File Saved with Date \ Time Stamp from report scheduler

I have a report that when exported from the report writer, it is saving the file as I need (name of report only). When it is ran from the web report scheduler to a saved folder on our shared network, it is adding the year, date, and time stamp in the files name. How do I get the system to send only the file name without the time stamps like it does when exporting directly from report writer.
