No errors or results are displayed when running a MetaMatrix Query against a WebService

Issue

• I'm running the below query and I get an empty result set.  I have the "Log XML Request/Response Documents" enabled and still I do not see the XML Request in the logs.

• Actually few of the parameters are optional when I checked in SOAP UI  but I was getting error in Designer when I didn't have them in where  clause, that's why I had it as empty. Having empty parameter values in  the query is same as not having them in the query.
