IDoc to SOAP Receiver Fault Message Handling?

Hi,

I am working on IDoc to SOAP Scenario (IDoc -> PI -> SOAP). It is in async mode without BPM. This works fine as long as there is no error on the SOAP receiver side. How to handle the falut message raised by the SOAP receiver and send it back the SAP ECC.

Do I need to use ALEAUD IDoc for this? If Yes, how to configure this to handle fault message? Is there any other way of doing it?

Could you please give steps to handle the fault message?

Thank you.

Regards,

Cdr.
