An attempt has been made to allocate a mapped conversation, but the remote system was expecting a basic conversation. CICS® supports only mapped conversations, so the remote system and program need to be changed.
This error can also occur if CICS receives a request from a remote system to attach a basic conversation
The communications conversation has not been started, or has been terminated.
Change the configuration and the program in the remote system so that it can accept a mapped conversation from your region. then rerun the request.
