This is done on the Interface tab as with other process data. There is a special section on the Interface tab for correlation data:
If you do not want a start message event to have correlation data, select the No correlation data initialization required check box in the Correlation Data section of the Interface tab. If you select this check box, you must ensure that correlation data is initialized (for example, using a script) before it is required in the process.
2. Click the Interface tab.
If the Interface tab does not display the Correlation Data section, make sure that the event or task you have selected is one of the types listed previously. Other types of event or task do not require correlation data and therefore do not display this section on the Interface tab.
3. Clickto select the correlation data that you want to associate with the event or task. The Select Data Field dialog displays the list of available correlation data fields.
− Correlate (Intermediate Catch Message Event and Receive Task Only) The specified incoming data is compared to that of existing process instances to ascertain the target of the request.
− Initialize Specifies that the correlation data is expected to receive its value from the incoming data. For a start message event, a process instance is started, then the correlation data field is initialized with a value from the incoming data.
− Join (Start Event or Received Tasks without incoming flow Only) Causes the correlation data (mapped from the input data) to be compared to the correlation data for any existing process instances. If no matching process instances are found, a new process instance is started. If the correlation data matches that of an existing process instance, the request is directed to that instance (a new process instance is not started).
6. If you want to configure the timeout of the correlation event, click the Resource tab. Expand Correlation Timeout and define the timeout you require.
