trigger em view materializada

Bom dia!

Alguém já teve problemas com a criação de trigger para uma view materializada ?

Eu criei uma TRIGGER para guardar um resumo dos dados da view materializada em uma tabela histórico. Porém após a criação da TRIGGER a VIEW MATERIALIZADA não atualiza mais.

segue erro ao tentar força a view com a trigger habilitada:

Erro ao iniciar na linha 240 no comando

BEGIN DBMS_SNAPSHOT.REFRESH( 'BACKLOG_INC_SLM'); END;

Relatório de erro:

ORA-12008: error in materialized view refresh path

ORA-04091: table KPIOPS.BACKLOG_INC_SLM is mutating, trigger/function may not see it

ORA-06512: at "KPIOPS.ATUALIZA_HISTORICO_INC", line 3

ORA-04088: error during execution of trigger 'KPIOPS.ATUALIZA_HISTORICO_INC'

ORA-06512: at "SYS.DBMS_SNAPSHOT", line 2251

ORA-06512: at "SYS.DBMS_SNAPSHOT", line 2457

ORA-06512: at "SYS.DBMS_SNAPSHOT", line 2426

ORA-06512: at line 1

12008. 00000 - "error in materialized view refresh path"

*Cause: Table SNAP$_<mview_name> reads rows from the view

MVIEW$_<mview_name>, which is a view on the master table

(the master may be at a remote site). Any

error in this path will cause this error at refresh time.

 For fast refreshes, the table <master_owner>.MLOG$_<master>

 is also referenced.

*Action: Examine the other messages on the stack to find the problem.

See if the objects SNAP$_<mview_name>, MVIEW$_<mview_name>,

 <mowner>.<master>@<dblink>, <mowner>.MLOG$_<master>@<dblink>

 still exist.
