This problem can occur on any platform.
Cube MIT_CUBE is based on ACCOUNTS and RESULTCODES dimensions.
The cube is mapped to ALL_RESULTS table, the dimensions are mapped to ACCOUNTS_DIM and RESULTCODES_DIM tables respectively.
The following query, that refers to the ACCOUNTS_DIM only (it does not refer to the other dimension table) is not rewritten to the cube organized materialized view CB$MIT_CUBE:
SELECT a.account_id, sum(r.count)
FROM accounts_dim a, all_results r
WHERE a.account_id = r.account_id
GROUP BY a.account_id;
DBMS_MVIEW.EXPLAIN_REWRITE (<above_query>, 'CB$MIT_CUBE') gives
QSM-01284: materialized view CB$MIT_CUBE has an anchor table RESULTCODES_DIM not found in query
