server to UDB

I'm trying to set up a linked server from sql server 2000 to udb 8.1.14. My selects to the UDB table work fine. Inserts/updates deletes fail. The insert returns - OLE DB error trace [OLE/DB Provider 'IBMDADB2' IRowsetChange::InsertRow returned 0x80040e53: The provider does not support the necessary method.]. Here's the insert format - INSERT OPENQUERY(TESTUDB3, 'SELECT * FROM TEST.T1') VALUES( '1','1','1','1','1'). Is this the correct format? Does the IBM provider allows updates?What happens when you try

insert into TESTUDB3.TEST.T1
VALUES ( '1','1','1','1','1')|||Same error.
