Compile Makes Materialized View Invalid When Access to Master Table Granted Via Role (Doc ID 781255.1)

Materialized view (MV) gets created without error. Its status is VALID in DBA_OBJECTS. 

'ALTER MATERIALIZED VIEW <MV> COMPILE' makes the MV invalid, DBA_MVIEWS.COMPILE_STATE 
shows COMPILATION_ERROR.

MV refresh does not change the status, after refresh the status is invalid if the status was invalid before refresh.
Similarly status remains valid, if the status was valid before the refresh.

Query in the MV's DDL runs fine as the owner of the MV.

If the MV gets invalid e.g. due to DMLs on the base table, neither ALTER  MATERIALIZED VIEW ... COMPILE, 
nor complete refresh makes it valid.
