 <title>Creating correlation sets</title>

 	<h1>Creating correlation sets</h1>
 	<p>Correlation sets are used to identify ongoing conversations
 		between a client and the BPEL process. Typically, a correlation is an
 		element in a message that uniquely identifies the conversation between
 		client and service; for example, an Order ID or Social Security
 		Number. This also identifies a specific process instance being managed
 		by the BPEL engine.</p>
 	<p>In many cases a single element of a message is not enough to
 		make it unique, so correlations can be defined as composites of
 		several fields. Since a conversation can involve many different types
 		of messages. Different correlations will need to be defined for each
 		message type.</p>
 	<p>
 		To create a correlation for a messaging activity (for example: <strong>Invoke</strong>,
 		<strong>Receive</strong>, <strong>Reply</strong>), select the activity and then
 		click <strong>Add</strong>  on the <strong>Correlation Detail</strong>  property
 		tab. This will display the <strong>Select
 				a Property</strong>  dialog.
 	</p>
 	<p>
 		<img src="../../images/reference/Handlers_07.png" alt="Select a Property" />
 	</p>
 	<p>
 		You can select an existing property defined in the WSDL or click <strong>New</strong>
 		to create a new WSDL property, which will display the <strong>Create
 		Message Property</strong>  dialog.
 	</p>
 	<p>
 		<img src="../../images/reference/Handlers_08.png" alt="Create Message Property" />
 	</p>
 	<p>Enter a name for the new WSDL property and its type. Either an
 		XSD simple type or an XML Schema element.</p>
 	<p>
 		Next, click the <strong>Browse</strong>
 		 button to select a type. This will display the <strong>Type
 				Selection</strong>  dialog.
 	</p>
 	<p>
 		Click <strong>New</strong>  in the <strong>Aliases</strong>  section to create a
 		new WSDL property alias.
 	</p>
 	<p>

 	</p>
 	<p>
 		Select either the <strong>Message
 		Type</strong> , XSD <strong>Simple
 		Type</strong>  or XML scheme <strong>Element</strong>
 		 radio button and click <strong>Browse</strong>
 		 to select its type. Then click <strong>OK</strong>
 		.
