Hi
In your custom event under the custom attributes section you create a new data type variable such as EXP_date_ and in the server method you can type
trunc(:NEW.EXP_DATE) 
In the event action conditions you can use the above EXP_DATE_ variable and match with trunc(sysdate) 
EXP_DATE_   = trunc(sysdate)
this way both date formats will match   . You can fill in the email and other details as needed
                
     
                                    
            Good morning,
The proposed solution did not work, but I solved this a different way. YOu need to create a custom attribute that will change based on sysdate. This is the trigger you use in the action.
I created DATE_MATCH and set the server method as: CASE WHEN &NEW:CF$_EST_INVOICE_DATE = TRUNC(SYSDATE) THEN 1 ELSE 0 END
Then I used DATE_MATCH = 1 to trigger my event action.
