How a job enters into the Request(REQ)Queue?

There are three ways, a job can enter into the Request Queue[REQ]. A job can be Scheduled, triggered or demanded out.

(1)   Scheduled(SSCN)-Jobs can be scheduled to run at a fixed time—For example, Reporting job runs every month-end at 08:00PM, Load jobs run every-day at 05:00AM and so on.

(2)   Triggered(AUTO)-A parent job X, when it runs to successful completion, can TRIGGER another child job Y. A TRIGGER automatically brings job Y into the REQ Queue.

(3)   Demanded(DEMD)-A Job X can programmatically demand out another Job Y.

For example,

  Job X has the following code:

    If Input File contains DATA

         Demand Job Y

    Else

          Continue

    End-if

Here, Job Y is brought into the Request Queue[REQ], only if the Input-file has data records. If the Input file is empty, if there is no data to process, the job is not demanded out, So, in this fashion, you can exercise more control, over how the job kicks off.
