506 NOAPHRESP Server does not support APH responses.
The Teradata Database does not support APH responses. This error can occur when a newer client version is interfacing with an older server version. As a matter of good programming practice, the client application should always verify (via DBCHQE) whether the server supports a given feature before attempting to invoke it.
Do not request APH responses unless both client and server components are capable of supporting it. Consider upgrading to a server version that supports APH responses if this feature is desired.
