Handle system errors in BPM

Question

I'm working on a BPM that may fail to perform some steps due to system errors. I can raise an exception if that happens, but what I'd like to do in the exception branch is to build a response message to the calling application that starts the BPM, declaring the reasons of the error. I can do that  giving a generic "system error" description, but I'd like to be more precise, and access the system error cause itself and add it to the message description.
Is this possible? How to make it?
Thanks in advance.

Hi,
    As per my knowledge we can raise System errors using Send step and Transformation Step.I dont think we can rise System errors using Control step.Control Step handles only Exceptions not System errors.(Confirm once).
But if you want to rise System errors go for Send Step Synchronous or Asynchronous.
Send Step Synchronous used when exception triggered by permanent system errors that occur in the pipeline or while transporting the message to or from the pipeline.Asynchronous Send Step:the exception will only be triggered if an error occurs during the transfer to the pipeline. Errors that occur during mapping in the pipeline, do not trigger an exception.
Transformation step used when to rise Permanent System error occurs.
