When Background task raises exception that is not handeled

Question

Hi,
I am using a background task that uses a method which does not handle exceptions raised by the function module it calls in turn. When such situation arises, i want to build some sort of exception handling mechanism in my workflow.
e.g, BG task uses method 1 that calls method 2. method 2 raises some exception which is not handled in method1 or method2 results into short dump. As a result of this situation Workflow bg task changes the status to ERROR and I want to handle such unplanned exceptions in Workflow.
Is there anyway for workflow to know (maybe some event) when one of it's BG task status changes to ERROR?
Thanks,
Saurabh

Hi,
Just use the exit_return macro in your method. See the following example.
BEGIN_METHOD 'Method_Name' CHANGING CONTAINER
**Data Declaration
**fetching data from container
CALL FUNCTION 'Function_module_name'
   EXPORTING
   IMPORTING
   TABLES
   EXCEPTIONS
     exception1 = 01
     OTHERS = 02.
   IF sy-subrc ne 0.
     EXIT_RETURN 9001 SPACE SPACE SPACE SPACE. 
                       "Define this event in the exceptions of the method.
   ENDIF.
Passing data to container
END_METHOD.
After doing these changes in your method, you will be able to see your exception in the outcomes tab of the activity. Just activate your exception there. You will get a new branch for this exception in your workflow. In this branch, you can determine how do u want to handle the exception.
Hope this will help you. Let me know if you have any doubt.
