R12.2 : custom triggers on edition tables

Hello ,

We upgraded to R12.2.8 from 11i  during the weekend.    We are need to replace a trigger and it is failing with

ORA-04095: trigger 'LASERFICHE_AI_TRG' already exists on another table, cannot

replace it

The command is CREATE OR REPLACE TRIGGER LASERFICHE.LASERFICHE_AI_TRG ..     BEFORE INSERT ON LASERFICHE.APX_LASERFICHE_STAGING

in DBA_Triggers , the table is editoned views.

1  select table_name, trigger_name from dba_triggers

  2* where trigger_name = 'LASERFICHE_AI_TRG'

SQL> /

TABLE_NAME

--------------------------------------------------------------------------------

TRIGGER_NAME

--------------------------------------------------------------------------------

APX_LASERFICHE_STAGING#

LASERFICHE_AI_TRG

question is should we replace the trigger in editon views or should we drop and recreate the trigger on table.
