The purpose of the trigger file is to indicate that the copying/loading of the main file has completed and that it is now safe to load the file. Secondly the trigger file may contain control sums to validate the contents of the main load file. This field should contain the full path name to the directory in which a trigger file is located on the Windows or UNIX systems. If this field and/or the 'Trigger Name' field is populated then the scheduler will look for this file rather than the actual load file.
