Yes it's possible. Open the stage properties, select the Inputs tab, select the Partitioning tab. Choose the partitioning algorithm from the drop-down list. On the Outputs tab you can set the Preserve Partitioning flag.

But just a word of caution!

Don't re-partition your data unless you really need it.

As partitioning is an overhead and if you do repartitioning it definitely reduces the performance of the jobs.

Report a bug in the version 8 client to your support provider. It works fine in version 7.5.2.

Contact IBM for patch ; it's a bug in the client software.

I have a workaround :

When the message appears, go to the stage tab. The message should keep on popping out. Keep pressing ENTER. At some point, DS lets you go out and when you come back in, the change is recorded.
