Replicating Oracle Partitioned tables into SQL Server

Hi,

     We have Oracle database with Partitioned tables and Partitioned Indexes.

     While creating transaction replication from Oracle 11.2.0.2 to SQL Server 2008 R2, it is not allowing to select those tables for replication and it is showing warning as "This table cannot be published because it does not have a primary key column. Primary key columns are required for all tables in transactional publications." even though that table having Primary Key.

     Can you please help me.

Regards,
