Answer 1

You can query data and also at the same time validate for example if a client exists, in a WHEN-VALIDATE-ITEM of an item do this:
BEGIN
     SELECT NAME
     INTO :CLIENTS.NAME
     FROM CLIENTS
     WHERE CODE_CLIENT = :CLIENTS.CODE_CLIENT;
EXCEPTION
     WHEN NO_DATA_FOUND THEN
     MESSAGE('NO CLIENT FOUND');
     MESSAGE(' ');
     RAISE FORM_TRIGGER_FAILURE;
END;the RAISE FORM_TRIGGER_FAILURE is optional.
