Workflow Soluiton

I am trying to extract the user and group selection workflow from SD.IncidentManagement project--the portion that lets you select a user or group to reassign a ticket to. I have the components in a new workflow, however, it appears I may be missing a library because I am receiving the following error:

Application Name : SD.AssetViewProject
Process ID : 384
Date :12/12/2013 2:00:08 PM
Log Level :Error
Log Category :LogicBase.ExecutionEngine
Machine Name :
Message :
System.Exception: data value AssignmentType does not exist
   at LogicBase.Core.Data.OrchestrationData.SetValue(String name, Object value)
   at LogicBase.Components.Default.Process.InsertDataComponent.Run(IData data)
   at LogicBase.Core.ExecutionEngine.SinglePathProcessComponentExecutionDelegate.Execute(IData data, IOrchestrationComponent comp, String& outputPath, IExecutionEngine engine, TLExecutionContext context)
   at LogicBase.Core.ExecutionEngine.AbstractExecutionEngine.RunComponent(TLExecutionContext context, IData data, IOrchestrationComponent comp)

Does anyone know what library I need to add in order to gain the functionality of using the AssignmentType feature?

Probably Symantec.ServiceDesk.Im.Core.dll is what you're looking for.

I conducted a search for this DLL, however, I have not been able to locate it. I also spot checked the SD.IncidentManagement project--the project where I am trying to resuse the reassignment workflow--and did not find the DLL in the project library.

SD-specific DLLs will be in the <install>/shared/customlib folder (pretty sure this is the place)

Also, the DLL mentioned above is a 7.5+ specific SD DLL... it doesn't appear in earlier incarnations.
