Correlating a response to an asynchronous callout request

The IMS application programs are responsible for correlating the response message to the initial asynchronous callout request. An IMS application can define a data element in the callout request, such as a message identifier or a unique callout request ID, that can be used to correlate a response with the initial input message.

After a response has been correlated to its initiating callout request, the response can then be correlated to the original inputting terminal or IMS Connect TCP/IP client.
