Hello Albert,
generally this the explanation for that error :
ORA-12015: cannot create a fast refresh materialized view from a complex query
Cause: Neither ROWIDs and nor primary key constraints are supported for complex queries.
Action: Reissue the command with the REFRESH FORCE or REFRESH COMPLETE option or create a simple
materialized view.
also to Diagnosing ORA-12015 fast refresh materialized view / complex queries that’s depend on the database version there is some restrictions ex:
Oracle10g – 10.2
——————–
Fast refreshable materialized views must be based on master tables, master materialized views, or synonyms of master tables
or master materialized views. Complete refresh must be used for a materialized view based on a view.
for further details about diagnosing refer to : Note.179466.1
hope this helpful.
