CPALookupException: Could not find channel in CPA Cache in PI 7.3

Hi,

I am getting below error in PI 7.3 when trying to send data from SOAP sender Adapter.

com.sap.engine.interfaces.messaging.api.exception.MessagingException: com.sap.aii.af.service.cpa.impl.exception.CPALookupException: Could not find channel in CPA Cache. Object ID: f3898d7d5ca3380a8aca739cc21b0cac. Cause: com.sap.aii.af.service.administration.api.monitoring.ChannelUnknownException: Channel was not found in CPA Cache: f3898d7d5ca3380a8aca739cc21b0cac due to: Got <null> from CPA-cache.

Steps

2.) Done full CPA Cache refresh

3.) Created communication Channel and ICO

4.) Activated

But when i checekd in communication channel i found above error.

Regards,

Anurag
