REST Sync to ABAP Proxy Sync / SOAP Async

[philipbahn]

Hello All,

I have already read many guides on Sync/Async scenarios, but none fit my specific requirement.

Given is a working solution with a Sync REST Sender with JSON conversion and a Sync ABAP Proxy Receiver. Request and Response in this scenario is working fine the normal way.

Now, the Sync Request should be sent to a second Async SOAP Receiver. For this I have configured a condition in Receiver Determination of the ICO:

• IF flag = X -> Sync ABAP Proxy Receiver
• IF flag != X -> Async SOAP Receiver

So Request goes EITHER to Sync ABAP Proxy with Sync Response the normal way OR to Async SOAP Receiver. If Request is routed to Aync SOAP Receiver, then some Dummy Response should be sent back to Sync REST Call. This Response can be static. The solution should work without BPM on PO 7.5 Single Stack.

I found many solutions using RequestOnewayBean and WaitResponseBean in Sender Channel to convert Sync Call to Async Call like here. But how can the Sync Route to ABAP Proxy and back still work with this approach?

Can this requirement be implemented without BPM?

Thank you for any help and suggestions!

Best Regards Philip
