Hi, iam facing the following error during adding a new column in replicated table:

ora-12012: error on auto execute of job 6
ora-23357: the propagator does not exists
ora-06512: at "SYS.DBMS_DEFER_SYS" line 1716
ora-06512: at "SYS.DBMS_DEFER_SYS" line 1804
ora-06512: at line 1

how to fix these errors.

One more question, can i add a table in replicated schema but this table I don't want to put in replication.

thanks,
