Missing Records in DBA_DEPENDENCIES When Mview Refers to SYS Schema's Objects
Last updated on FEBRUARY 04, 2013

Information in this document applies to any platform.
All related entries are missing from DBA_DEPENDENCIES and USER_DEPENDENCIES when a materialized view references base objects in the SYS schema. This includes DUAL.
For example, if a query selected from table A, did a UNION ALL with table B, and did a UNION ALL with DUAL, none of the tables, including A and B would be referenced in DBA_DEPENDENCIES. Removing the last UNION ALL with DUAL would let tables A and B show up in DBA_DEPENDENCIES.
