@?/rdbms/admin/utlxmv.sql -- Will create default MVIEW capability table

EXEC dbms_mview.explain_mview('SCHEMA.MVIEW'); -- Explain mview
There are other arguments to it as well

 select * from sys.mv_capabilities_table; -- see the report post explanation


Reference : https://docs.oracle.com/cd/B19306_01/appdev.102/b14258/d_mview.htm#CEGGEHHC

Some other SQLs that may help

On Source

SELECT b.master,
       a.owner,
       a.name,
       A.SNAPSHOT_SITE,
       to_char(B.CURRENT_SNAPSHOTS,'yyyymmdd hh24miss')
  FROM DBA_REGISTERED_SNAPSHOTS a, DBA_SNAPSHOT_LOGS b
 WHERE A.SNAPSHOT_ID = B.SNAPSHOT_ID;


On target

SELECT owner,
       mview_name,
       master_link,
       refresh_mode,
       refresh_method,
       last_refresh_date
  FROM DBA_MVIEWS

Often a status of "Invalid" for materialized views simply means that a base table the view is built on has been updated and the view has not been refreshed.  In my opinion, Oracle should not report these views as "Invalid" but rather something like "Stale" or "Needs Refresh".

So no, you may not be able to easily find a reason for why these views are "Invalid" other than the fact that some data has changed in the underlying table(s) for the materialized view.
