Backup Exec 2010 custom reports

I had found an old thread asking this but there was no reponse.

Please could anyone explain the "Detail Job Type" field is displaying results such as 200, 600, and 1000. 

I have been sent dome job reports but they seem to have multiple entries for hte same job.  Maybe they are parent/child processes but it is driving my mad now knowing.

Any help would be appreciated.

Thanks

Andy
