Hi Erva
Your Receiver Configuration object has the same values as what was described in the error message, so the only thing I can think of if cache problem.
Can you check in SXI_CACHE, and search that the corresponding object is listed under the Receiver Agreement node?
Another curious thing, in your earlier screenshots for the pipeline, did you provide it from a message that is in error? If it is in error, there should be an Error node in the SOAP Header.
If nothing else works, you might want to consider changing this to an ICO as suggested by Hareesh (unless there is some limitation there which requires you to run it as a classical configuration.)
