Hi Upendra,

Please check your changelist in ID if you have activated the same in there and also check your cache notification. if the problem still there you can run a JAVA level cache refresh.

Thanks

Hi Upendra,

You can check this in a different way if it is still failing after the JAVA restart. If you have any Decentral Adapter Engine for this landscape and Env. you can change the Adapter Engine type in the configuration of the communication channels in ID and then you can check if these two communication channels are showing in the RWB of that Decentral AE

Thanks
