| ERROR | primary key or object ID is undefined for table or materialized view string |
| CAUSE | Trying to generate replication support for a table or materialized view without a primary key (as defined by a constraint or dbms_repcat.set_columns) or an object ID. |
| ACTION | For a table, add a primary key constraint or define a primary key using dbms_repcat.set_columns or use object tables. For a ROWID materialized view, set min_communication to false or use primary key or object ID materialized views. |
