Hi All,

It's a property of DataStage in which it combines two or
more Operators into a single Process.
You can explicitely enable/disable it with the help of
APT_DISABLE_COMBINATION environment variable at the job
level or at the Project level as well.
At stage level also you can enable/disable it:
In Stage properties>> Advance>> Operator Combinality.
By default it's Auto, so that datastage will decide whether
to combine or not.

You can see this combinality behavior by using the
following Environment Variable:
APT_DUMP_SCORE

For further queries, write me @ ankitgosian@gmail.com

Cheers,
Ankit :)
