This is an issue specific to MVIEW containing join conditions.
Wrong result from mview containing joins after complete refresh.
Example of such a select query for reference:
FROM TEST_JMA1 P
WHERE NOT EXISTS
FROM COMPANIES_MAPPINGS CM
WHERE CM.COMPANY_TYPES_ID = 1
AND CM.DELETED = 'N'
AND ( CM.COMPANIES_ID_1 = P.COMPANIES_ID
OR CM.COMPANIES_ID_2 = P.COMPANIES_ID));
This is identified during the upgrade process from 10.2.0.5 to 220.127.116.11.
