This is solved executing a Full Refresh of server, accesing to URL http://10.10.1.74:50000/CPACache/refresh?mode=full

But we want a solution permanent.

Thanks and Regards.-

Hi,

Check the RFC_ERROR_COMMUNICATION again. It seems that after upgrade you have not updated the "Application Server", "System Number", "Client", User id & password.

sorry I haven't lookd those last lines..

So it seems a cache issue, due to which it happens and when you refresh the CPACache then it starts working again.

Regards,

Sarvesh
