A 
Batch Process Group is a group of 
Batch
        Process entries that are executed sequentially at a specified time. The time at
      which a 
Batch Process Group is executed is specified us
        
cron notation.
CAUTION:
Due to the date/time nature of the
        processing it is recommended that a long running process not cross 2:00 A.M. and possible
        not be scheduled earlier than 2:15 A.M. due to Daylight Savings Time issues. Although most
        operating systems will account correctly for Daylight Savings Time, this has not always been
        the case. 
All the output files created by each Batch Process are grouped into
      one file and will be emailed if an email address is specified on the Batch Process
        Group.
    The intent for a Batch Process Group is that it be executed using the
        cron facility.  However, if need be, it may be executed using the Staff
      Portal.
