ORA-00942 while creating materialized view


I hit following problem while creating the materialized view with option refresh fast although   SCHEMA2.TABNAME  exists and SCHEMA1 user has select privilege on  it

CREATE MATERIALIZED VIEW SCHEMA1.MVIEW ....
SELECT .... FROM SCHEMA2.TABNAME....

ORA-12018: following error encountered during code generation for  "SCHEMA1"."MVIEW "
ORA-00942: table or view does not exist

Problem is not the source table itself but the materialized view log table created before. In order to solve the problem you should identify  materialized view log table and give select permission to  materialized view owner

select LOG_TABLE from ALL_MVIEW_LOGS where log_owner=' SCHEMA2' and master='TABNAME'

grant select on  SCHEMA2.LOG_TABLE to  SCHEMA1;
