To test a standalone decision service component by using Oracle Enterprise Manager Fusion Middleware Control, you must provide the name of the decision service as the value of the payload name field in the Test Web Service page as shown in Figure 25-21.

'name' in payload should be the decision service name as can be seen in the sample .decs file in Figure 25-22.

Without the decision service name, it is not possible to invoke the standalone decision service with just the payload and endpoint details.
