Structure Window and Workflow

Suppose that you have a two-node workflow simple consisting of a Data Source node and a Classification Build node: two node workflow with data and model node
The Structure window for simple is structure windo for workflow simple

If you select an item in the Structure window, the corresponding item is selected in the workflow. For example if you go to the Links folder and select From "DATA_MINING_BUILD_V" to "Class Build", the link between the two nodes in simple is highlighted.
