IDOC to Webservice to Email - Async to Sync Scenario

Question

Dear Experts,
I have a scenario: IDOC to Webservice (Async to Sync)
The response from the webservice needs to be sent via email. So I have a Email channel added to the Business service (ECC).
I tried this with BPM, but it does not work complaining about multiple receivers in a sync receiver interface.
Anyone has done similar to the above?
1. Using BPM?
2. Without BPM?
Thank you.

Answer 1

Thank you for the reply. This is what I have:
Repository:
1. Async ABS Interface for webservice request message
2. Sync ABS interface with webservice request message and response message
3. Async ABS interface for the reposnse message
5. Async IB interface for hte email message
4. Message mapping between IDOC and webservice request message
5. Message mapping between webservice response message and email message
6. 2 Interface mappings with the above mapping objects
7. Integration Process BPM with Receive step (Async w/s req), Sync send step (w/s req and respp) and Async send step (w/s response)
Directory:
1. Receiver agreement with BPM as sender and Webservice as receiver with SOAP receiver channel
2. Receiver agreement with BPM as sender and ECC as receiver with email receiver adapter
3. Interface determination for request mapping
4. Interface detrmination for response mapping
5. Receiver determination with ECC as sender and BPM as receiver
6. Receiver determaination with BPM as sender and Webservice as receiver
7. Receiver determination with Webservice as sender and ECC as receiver
is the above sufficient and right?
Thank you.
