Create an attached service

Create a service to pass parameter values from the message event to the business process definition (BPD).

The UCA that you attach to the message event needs a service to pass the parameter values from the runtime message to the BPD.

For intermediate message events like the one in this sample inbound integration, even if no parameter values are being passed from the message event to the BPD, you must map a UCA input variable to a local variable to ensure that the correct running instance of the BPD resumes execution upon receipt of the message event.

Procedure

1. Create a General System service and name it My UCA Handler or something similar. (If you need detailed instructions, see Create a service.)

2. Use the Sequence Flow tool to connect the Start Event and End Event components in the service diagram. Because this service is used to simply pass values, you do not need to add any service components to the diagram.

3. Click the Variables tab.

4. Click the Add Input button and replace Untitled in the Name field with someString.
5. Leave the variable type for the input variable set to String.

6. Click the Add Output button and replace Untitled in the Name field with someString.
7. Leave the variable type for the output variable set to String.
8. Save your work.
