Hi all,
I am trying to building a web service through SAP XI exposes the function module SAP_WAPI_START_WORKFLOW as a web service, which when executed starts the WS20000391 (Schedule Manager) workflow to start a job. But, i get this error:

Hi,
1. Test the web service through using test tool like XMLSpy.And observe
whether you are getting back the response. And you should deploy the
XMLspy on the same network where your XI box is present.
2. If the response is coming back then you can try increasing the time
out value for the receiver adapter and test it.
Please refer to the Note: 856597[FAQ XI 3.0 SOAP Adapter]
How i can configure the time out value of my receiver adapter.
A: Yes. The default timeout value for outbound calls is 5
minutes. You can increase this value by setting parameter
XMBWS.Timeout in the module parameter table of the SOAP adapter.
The value must be given in milliseconds. For example, value
600000 represents the timeout value of 10 minutes. This parameter
is not recognized in systems prior to SP13.
Check it out,
