Unable to retrieve Channel object from CPA Cache - Error in Proxy Sender Channel

Hi All,

I am working on a Proxy to SFTP interface in SAP PI 7.31(Single Stack).

While I trigger a proxy message from ECC system, I am getting the below error in SXI_MONITOR of ECC system and also in the Sender Proxy channel of the SAP PI system.

com.sap.engine.interfaces.messaging.api.exception.MessagingException: com.sap.aii.adapter.xi.routing.RoutingException: Unable to retrieve Channel object from CPA Cache

This interface getting executed successfully one week back.

Please help in resolving this issue.

Thanks in advance.

Regards,

Subbalaxmi Musunuri
