No Workflow Message is Sent

A response is returned if the request is sent for a user that has no application connection registered yet.

no workflow message is sent because no device is found 
to send the notification
Explanation: The server could not find a matching application connection for the user identified in the Hybrid App DCN request. In this case, the response is similar to:
{"id":"dcntest_test_001","success":false,"statusMessage":
"no workflow message is sent because no device is found to send the notification"
,"result":[{"id":"dcntest_test_data_1","success":true,"statusMessage":""}]} 
Workaround: Invoke any other SAP Mobile Platform application (for example, a client-initiated or server-initiated workflow application, or a native application), which maps an SAP Mobile Platform user to a messaging synchronization device user, then send the DCN with
"to":" < this user > "
