Successor & Triggered both are the jobs starts execution only on completion of a specified jobs, the difference lies in Successor jobs dont use any output from its predecessor jobs.

One use of successor jobs is in checking that a predecessor has run within a specified number of hours.

Triggering can be set at the dataset level too.Once the job creates a particular dataset then it will trigger the job.This factor is one of the differentiation that it has with the successor job.

Hi,

Triggered means once Job A is completed Job is going to trigger.
Successor means Before execution of Job B it checks whether Job A is completed or not.

Let me know if you still have any doubts.

Regards
Kalyan.

Hi Kalyan,
Thanks for your response.
But in both the case (Triggering and successor) jobs has to wait to complete the predecessor jobs.

Could you please explain me when we can use triggering and when successor as both are same.

Thanks & regards

A difference b/w Successor & Triggered Jobs is that, Triggered Job gets start immediately after complition of its earlier job. But It is not a compultion to a successor job, It will get start at Its own time.

Yeah, Its correct. In both cases later job waits completion of earlier.

Suppose, Job A, runs 11:45 AM, needs two dataset to proceed.
One of it, from Job P, which it gets everyday 11:00 AM, other from Job Q, at 11:30 AM. So Job A can be a successor of Job P, but can't be triggered by Job P.

I hope it'll make U clear.

Priyesh.
