Transformer stage strange Issue

Hi

We are facing one strange issue from Transformer stage.
We are in the process of migrating from Data stage 8.1 to Data stage 9.1. One of our DS job no data pass through after transformer stage. But the same job running and passing the data from 8.1 job Transformer stage.

I did some fix and workaround. I have removed/replaced with new transformer stage in DS 9.1 job and it works fine and data also passed into next stage.

Is this any bug or issue with Transformer stage.

Thanks

Man

Did your "some fix and workaround" involve more than replacing the transformer with an exact copy of itself? I'm also assuming there is a constraint on the output link and that evaluating to false before your change is what caused it to not "pass" any data - can you confirm? I'm guessing a code issue in the constraint expression, something that was tightened up in the new release and which required a fix to allow data to pass again.

I'm not aware of any bugs in the stage. Maybe it has something to do with null handling behavior changes after version 8.1. If you are able to reproduce the difference and narrow it down further, please share the details.

When you exported from 8.1 to 9.1 did your crew "include dependent objects" or those read only objects?
