Split message using BPM

Hi Experts

I am getting the request through HTTP which i want to split using BPM and send each splitted message to synchronous step and get the response for each splitted message

I have gone through the following blog

/people/sudharshan.aravamudan/blog/2005/12/01/illustration-of-multi-mapping-and-message-split-using-bpm-in-sap-exchange-infrastructure

I am able to split the message into multiple messages but unable to send each splitted message to synchronous step and get the response.

I am getting " NO Receiver Found" error.

How to send each splitted message to synchronous step and get the response.

Please suggest.

Regards
