Alerts on mapping error from BPM

Question

In my BPM, when I use 'Throw Alert' via control step before transformation, it creates an Alert.
What I would like to do is to Throw Alert when there is a mapping error. And in order to do this, I created an exception block within my transformation step and inserted an exception handler. And in the exception handler, I created control step with 'Throw Alert'.
When there is a mapping error, I do not get an Alert but throws an exception.
Is there anything I'm missing.
Thank you,

hi,
Following is the required order
1. Create a block Step BLK_TransformationExceptions.
2. In the properties of BLK_TransformationExceptions
    define an exception TransformException
3. Add Exception Branch into block step.
4. Set the exception handler to TransformException
5. Add your transformation step into block step.
6. In the properties of transformation step set the
    system exception to TransformException(your custum
    exception)
5. Move your alert login into the exception handler.
