Hierarchical stage failing in higher environment

[midmaxds]

Hi,

We are testing a datastage job with Hierarchical stage in it which generates an XML.
In the Dev regions, we never faced the below error. But it is happening in higher environments. Tested with same data in both regions.
Can some patches help? Kindly advise.

A null pointer exception? Involve support.

...but also look at the data that you are feeding it. In production, is it possible that you have a different source? or different rows? At least as a test, use "the same" input as you do in dev, to eliminate any possibility that something in the data is throwing off your assembly logic or impacting a particular node/element, etc. in the xml that is being crafted. There are many things that could impact your regroups or other assembly logic that could be thrown off by data values that you weren't prepared for.

Thanks, Ernie. We have involved support now.

Meanwhile, we pointed to the PROD source from non-prod region and triggered the job. It ran fine without any issues. This makes us think that there is something missing in the PROD IIS server.Your thoughts too, please.
