Job-Dependency Processing Rule

Before a job can run, all jobs on which it depends must run successfully, at a time later than the dependent job’s synchronization time. The synchronization time is either the last time the job’s dependency list was modified, or the last time the job completed — whichever occurred most recently.

For example, if Job C depends on Jobs A and B, then Job C will not run until Jobs A and B have successfully run following Job C’s synchronization time. If Job D is added to Job C’s dependency list, then Jobs A and B, as well as D must run again before Job C can run. This is because Job C’s synchronization time would reflect the time that Job D was added to its dependency list.
