Hi Trevor,
Can you provide us a sample for invoking this method: helpdesk::logAndAssignNewCall and please add complex parameter for additionalvalues. I tried to mimic your code and came up with this but the opencall.itsm_title is not updating.
xmlmc.AddParam("callClass", "Service Request");
xmlmc.AddParam("customerId", "******");
xmlmc.AddParam("groupId", "******");
xmlmc.AddParam("analystId", "******");
XmlmcParam param = xmlmc.AddParam("additionalCallValues");
param.Add("opencall", "<itsm_title>TANG</itsm_title>");
sendTextToOutputBox(xmlmc.GetParamsXML());
xmlmc.Invoke("helpdesk", "logAndAssignNewCall");
Thanks,
Nico
