Adding Parameters to a Business Process Service Operation

When you create a business process service, a single default operation is generated for the service interface. You must add its parameters and define their properties.

As you develop the business process, you can add operations to the service and add or edit parameters using the Business Process Variables section on the Business Process page or by dragging a Receive/Request or Request/Response icon from the Interface tool palette onto the business process canvas.

  1. Open the Service editor.
  2. To select the operation, expand the Operation Parameters section.
  3. Click Add to add parameters to the service operation.
