Test Configuration Error---Internal Error Null

Hi Experts

I am configuring the Standard Proxy-Proxy Interface for SRM to ECC Integration. I had configured the interface and when trying to check the configuration in Test Configuration, its through error as Internal Error Null at Receiver Determination. I had tried will different scenario, but its the same error. I had processed the message from SRM to PI and checked it failed in MONI saying no Receiver Determination Found. But i had configured it correctly.

Please let me know if anybody else had faced the same issue or if someone can help me in identifying the issue.

Thanks&Regards
