What is a Correlation Set

Select properties defined in a WSDL to use in a correlation set.

A correlation set is a set of properties shared by messages. A correlated message data that is the same as that in all other messages in the set. Since the element names of each message can be different, you need a mechanism to match up the same piece of data among the messages.

How does the mechanism work? For each correlation set, you create a data property, such as customerID. For each message being correlated, you create a property alias for a message part, such as a Receive's message part named custID, an invoke's input message part named CustomerNumber, and so on.
