    Transform Variables node may not detect changes in Input Data source

      Product: Enterprise Miner
    Component: Transformation node
     Priority: ALERT

      Consider the following flow in Enterprise Miner:

      Input Data Source --> Transform Variables --> a modeling node

      Suppose a variable X exists in the Input Data Source. In the Transform
      Variables node, create a transformation of X. Go back to the Input Data
      Source node, and reject X. Now run the flow from the Transform Variables
      node. The Transform Variables node should drop the new transformed
      variable, however it does not. It incorrectly passes the transformed
      variable to the modeling node. Hence the results of the modeling node
      are incorrect, and so are any results following the modeling node
      (assessment, scoring, etc). There are no warnings or errors indicated.
      The only way to tell if the problem has occurred is to open the modeling
      node(s) and verify that the transformed variables are not used as

      To circumvent the problem, open the modeling nodes and verify that the
      list of input variables is correct.
