Starteam SDK Linking Impacts to CR's

I am writing a report using Word and VB macros. I can connect to Starteam and find the CR folder but cannot identify which items in the folder are CR's and which are impacts and how to associate the impacts with the correct CR's. Any help would be appreciated.
After connecting to the Starteam server I am using this code to get the correct view.

Set oCR = oServer.typeForName(oServer.TypeNames.CHANGEREQUEST)
Set oFLM = oFLMFact.Create(oView)
oFLM.includeFolders oView.RootFolder, -1
Set oCRLM = oILMFact.Create(oCR, oFLM)
