ORA-23380: propagation mode "[string]" is not valid
Cause: The specified propagation may be misspelled, or is not supported. For materialized view sites, all materialized view object groups at the same materialized view site with the same master object group must all have the same propagation method.
Action: Refer to the manual on replicated data for valid propagation modes. For materialized view sites, also ensure that the propagation modes of all materialized view object groups with the same master object group are the same.
