I know nothing about SOAP. What is the following doing, and what do I need to do to get some different tables/fields included with whatever the heck it's returning?

loSOAP = m.oSOAP
loSOAP.ClientProperty("ServerHTTPRequest") = .T.
loSOAP.mssoapinit("http://pfgrduebs003/WebServices/PRRData.asmx?WSDL","PRRData")
