No Workflow Message is Sent

A workflow DCN response is returned if the request is sent to a device that has no users mapped.

no workflow message is sent because no device is found 
to send the mail
Explanation: When a new message-based synchronization Workflow device user is created and registered from Sybase Control Center, by default there are no users mapped to the device (Device Users > Devices > MBS user name > Users.... In this case, when sending a Workflow DCN request, 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 mail"
,"result":[{"id":"dcntest_test_data_1","success":true,"statusMessage":""}]} 

Workaround: Invoke any other Unwired Platform application (for example, a client-initiated or server-initiated workflow application, or a native application), which maps an Unwired Platform user to a MBS device user, then send the DCN with
"to":" < this SUP user > "
