I am getting this error while testing a SOAP sender HTTP SOAP to SOAP receiver HTTP XI from web service navigator. We are in the process of migration from PI 7.3 to PO 7.5. Same web service was working fine on PI 7.3 system. Please help.

Thanks Raghuraman , Viktor and Faith for quick reply.

When I checked the detailed trace as suggested by Viktor, S_Service authority was missing on the user that I was using to connect to my backend ECC system.
