AutoCAD Inventor :: Getting Virtual Components To Be Counted / Included In An EXCEL BOM

getting virtual Components to be included in an Excel output of an assy BOM. I have an existing macro (see code below) that exports the StockNumber, partNumber,Description and an occurrence count of each item to an Excel spreadshet. It all works fine except for Virtual Componenst which are not included. It seems that because no file is created that the VC item can't be included in the Excel doc.

Sub Assy2Excel()
Dim oAssDoc As AssemblyDocument
Set oAssDoc = ThisApplication.ActiveDocument
Dim SIPropSet As PropertySet
Set SIPropSet = oAssDoc.PropertySets.Item("Summary Information")
Dim rev As String
rev = SIPropSet.ItemByPropId(kRevisionSummaryInformation).Value
If oAssDoc.DocumentType <> kAssemblyDocumentObject Then
MsgBox "The Active document must be an 'Assembly'.", vbExclamation
Exit Sub
End If

If MsgBox("The generated list is for the use of the Purchasing Department. It counts all of the BOUGHT & MADE parts in the assembly. Some manual editing will be required to 'clean up' the list.

", vbYesNo + vbQuestion) = vbNo Then
Exit Sub
End If
Dim oDocs As DocumentsEnumerator
Set oDocs = oAssDoc.AllReferencedDocuments
