The following error can occur when creating a materialized view, where the FAST REFRESH option is chosen, and the Master Table is located on a remote database. Thus utilizing a <DBLink_Name> in the mview definition.
WITH PRIMARY KEY
select * from testmv.<MView_Name>@<DBLink_Name>;
ERROR at line 9:
ORA-12028: materialized view type is not supported by master site @<DBLink_Name>
No changes as such. The issue only occurs for non local mviews (Master table on a remote database) where a Database Link is used in the mview definition.
