Hi Anusha,

Try the following

Stop and start the communication channel..

Please check the communication channel status if no status is available, perform CPA cache refresh.

Perform SLD cache refresh from ID.

Refer the below notes

Channel Monitoring shows "Channel has internal error"

Hi Anusha

Check if any patches were applied recently.(Deployed version should match PI version)

Check if the MDM_JAVA_API is exist on the server.

Logon to NWA through http://host:port/nwa/app-modules and check if "tcmdmadapter~svc" module is started.

I dont have access to any 7.0 system to login and check. I am working on 7.4.

You should be able to see it in the following path.

http://<host>:<port>/nwa

--> operations --> Systems --> Start & Stop --> Java Applications. search for tc~mdm~adapter~svc

pls ask your basis team to do a complete system restart of both ABAP and JAVA stack, and see if this issue gets resolved.

pls check with basis team if some patch upgrade was done yesterday.

also the default trace and application log files in /usr/sap/SID/DV*/j2ee/cluster/server0/log folder may have some information as to what error has occurred today.

I have the same issue. Any idea what are steps that I need to take to solve this issue. We are using the MDM sender Adapter for the first time in our SAP XI dev box.
