Sync or Async process?

Hi All,

 

I have a proxy to Web Service interface, where I am using a SOAP Lookup UDF to send the request and catch the response from the WS due to security header items required.

I have 2 options to build this interface:

 

1) Asynchronous: SAP proxy request --> mapping1 (proxy to  WS structure) --> mapping 2 (WS structure to SOAP Lookup to SAP proxy response)

2) Synchronous: SAP proxy request --> mapping 1 --> mapping 2 --> SAP proxy response

 

For item 1, I need to send back the proxy request on the response, so I tried to add it as multiple messages but I am getting the "could not find message mapping" error.

 

For item 2, when I test through Operation Mapping I am unable to generate the first target structure.

 

Is anyone able to let me know how the design for both items should be?

Please notice that I will like to avoid BPM if possible on these requests and I will not use Java mapping.

I'll be glad to read different options.

Thanks!
