PI 7.1 - Multiple Operations - NO_RECEIVER_CASE_ASYNC

Hello All

I am using PI 7.1, Proxy to JDBC scenario. I a trying to use a single Service Interface with multiple operations (Customer, Vendor). When I test the scenario I am getting the error "NO_RECEIVER_CASE_ASYNC" at SXMB_MONI. Receiver Determination is configured as Operation Specific. However this error occurs.

Has anyone who could help me on this?

Thanks
