SQL0204 - Function not found using a local UDF with a ALIAS pointing to a remote system

All,

I created a UDF that does some character manipulation..

I tried to use it on a column in remote table via an SQL ALIAS.

select locallib.myudf(mydata)
from locallib.myalias

But I get a SQL0204 - MYUDF in LOCALLIB type *N not found.

Same error with this
select locallib.myudf('TEST123')
from locallib.myalias

But this works.
select locallib.myudf('TEST123')
from sysibm.sysdumm1

So my UDF is fine, I'm calling it properly. I think I'm hitting a
limitation in the support for remote tables.

Can anyone confirm? And is there some way around this limit...other than
copying the remote file to the local system?

Thanks!
Charles
