Issue in idocs sent through XML HTTP port

Hi All,

I'm currently working in PI 7.3 dual stack. There is an issue with the CREMAS and MATMAS idocs that are sent from ECC systems. They are being sent through XML HTTP port to PI.

When reaching PI, failing in moni with error "No receiver could be determined". I have checked the message header and the receiver determination, no issues with that.

But when I post the same messages from PI integration engine in RWB, they are getting processed successfully and sent to the corresponding receiver system. So what is the actual problem here? I'm not able to locate the issue. Please help.

Thanks,

Jegatha
