The exit can order a report decollating mission depending on job name, step name, DD name, and so on.
This is useful for:
Processing jobs which run several times a day and which write all their reports to CDAM. In this case, the exit orders a new report decollating mission for each run of the job.
Processing jobs which produce CDAM files depending on the input which the jobs receive. In this case, the exit orders a report decollating mission when a CDAM file is created. When the job does not create a CDAM file, a decollation is not ordered.
The CTDX018O member in the IOA SAMPEXIT library contains a sample exit that orders a report decollating mission when the CDAM file is created.
