Issue with WF container elements using OOPS

Hi Experts
          I am using a method in a class to create invoice .

         Currently,if any user is locking the delivery, I have set temporary error and after failing 3 attempts,messages are sent to container and

         WF is completed status.

            RAISE EXCEPTION TYPE ZXXX_TEMP_EXC which has a super class CX_BO_TEMPORARY exporting mesage = ex_message

         But my requirement is to make WF in error by capturing the error for message in container.

         After 3 attempts,I raised exception

               RAISE EXCEPTION ZCX_BO_ERROR which has super class CX_BO_ERROR exporting message = ex_message,

          My WF is in error status whereas error is not captured in container elements.

          How can i achieve this functionality?

         Transporting error messages to WF container and set WF in error status

Thanks,
Madan
