Hi,

I have managed to add & remove Custom references with the interface "IEdmEnumeratorCustomReference5". However I can not determine how I can control the Quanity or the function that adds the reference to the BOM side of things.

Public Sub AddReference(ReferenceFile As EDMFile, ByVal UnlockFile As Boolean)
        Dim CheckFile_IN As Boolean
        If Not Me.IsValid Then Exit Sub
        If Not _File.IsLocked Then
            If UnlockFile Then
                _File.edmFile.LockFile(_File.edmFolder.ID, 0)
                CheckFile_IN = True
            Else
                Throw New Exception(_File.edmFile.Name & " was not checked out.")
            End If
        End If
        Dim mainFile As IEdmEnumeratorCustomReference5 = _File
        Dim File2 As IEdmFile7 = ReferenceFile.edmFile
        Dim Folder2 As IEdmFolder5 = ReferenceFile.edmFolder
        mainFile.AddReference(File2.ID, Folder2.ID)
        If CheckFile_IN Then
            _File.edmFile.UnlockFile(_File.edmFolder.ID, "File reference added")
        End If
    End Sub
    Public Sub RemoveReference(ReferenceFile As EDMFile, ByVal UnlockFile As Boolean)
        Dim CheckFile_IN As Boolean
        If Not Me.IsValid Then Exit Sub
        If Not _File.IsLocked Then
            If UnlockFile Then
                _File.edmFile.LockFile(_File.edmFolder.ID, 0)
                CheckFile_IN = True
            Else
                Throw New Exception(_File.edmFile.Name & " was not checked out.")
            End If
        End If
        Dim mainFile As IEdmEnumeratorCustomReference5 = _File
        Dim File2 As IEdmFile7 = ReferenceFile.edmFile
        Dim Folder2 As IEdmFolder5 = ReferenceFile.edmFolder
        mainFile.RemoveReference(File2.ID, Folder2.ID)
        If CheckFile_IN Then
            _File.edmFile.UnlockFile(_File.edmFolder.ID, "File reference removed")
        End If
    End Sub
