I am getting this error while executing a webservice model.
Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.XmlUnmarshalException: XML Deserialization Error. Empty node passed to deserializer [com.sap.engine.services.webservices.jaxrpc.encoding.primitive.DateSD] which is not acceptable.
Some time it is executing well and result is coming.
Some times it is showing the above error.
If it always shows XML Deserialization Error .... i will Reimport the model.
But some times it is working.
Can any one guide me in this issue.
