Load From Partitions Across Federated Connection

I have a production and a test database and I need to pull 25% of the data on the production table to the test table. I have a nickname on the test table pointing to the production table and when I try to use:

select * from <schema>.<prd_table> where dbpartitionnum<part_key> in (1,2,3,4)

I get an error: Invalid use of the row based funtion: SYSIBM.DBPARTITIONNUM.

Is this due to the fact that I'm trying to pull across a federated connection?

Of course, it works fine if working on local databases.

Any help would be appreciated.

Thanks...db2new
