RFC Sender - lookup of alternativeServiceIdentifier via CPA-cache failed

Question

Hello,
I am using RFC Sender for a scenario and while sending message I got following error. I found this error while monitoring communication channel. I looked at several posting on this issue and tried with both checking  and not checking check box of advanced mode (RFC sender communication channel configuration). I am getting the same "lookup of alternativeServiceIdentifier via CPA-cache failed" error. How did you resolved?, please let meknow.
Did any one come across error

run tc SXI_cache on the XI
