CHANNEL_DETERMINATION_FAILED error in production environment

Hi Experts,

We are in support stag and we are getting CHANNEL_DETERMINATION_FAILED in production environment(PI 7.11). We got this error twice in a year Its a Synchronus interface, non-sap to APO system.

We require 4 to 5 hrs of to run entire process chain to process data. When ever we are getting we are re sending request from non-sap. We are loosing precious time of 4 to 5 hrs. So, we want to find out the reason and resolve this issue.

Can anyone help me in resolving this error?

Thanks in advance.

Regards,
