Add shipment Cost Action Check is not working

Summary:

Add shipment Cost Action Check is not working when I have put the action check for Level and User Role ID, I am trying to prevent Carrier to not add same accessorial cost (Acc Code TONU) for the same shipment if it is already exists. Carrier is editing the shipment and clicking on "New Shipment Cost" which is available on financial tab. User role Exists in Servprov domain and I have put the action check in main domain where transactional data exists.

I have this saved condition

SELECT '1' FROM DUAL WHERE NOT EXISTS (SELECT 1 FROM SHIPMENT_COST WHERE SHIPMENT_GID = ? AND ACCESSORIAL_CODE_GID ='DRISC.TONU')
