The schedule run report file is a text file that holds information about the schedule run.  The name of the file depends on the dataset you are logged into and is in the format "Schedule_DatabaseName.TXT where DatabaseName is the name of the database.  The schedule run report is written to the Export folder.  Note that if you are appending to the schedule run report (set in Schedule Options) the file size will continue to grow until you either delete it or uncheck the option enabling the next schedule run to replace the file.

After a schedule run, you should check the file to see if there are any errors that require your attention.  See Scheduling on how to view the schedule run report from within DMS, or you can use a text editor to view the file.
