ORA-30505

system triggers should not reference a column in a WHEN clause

Cause

An attempt was made to use a WHEN clause to reference a column with a system trigger, but this type of trigger is not supported because a system trigger does not have a base table.


Action

Change the WHEN clause to an appropriate clause.
