After you specify a tree type and a unique format tree ID on the initial screen of the DME Engine, the DMEE: Create Format Tree <format tree> screen appears. It is divided into three parts:
On the left side of the screen, you define your format tree by inserting nodes in a hierarchical structure.
When you insert a node in the format tree, detailed information is displayed to the right of the tree in the top frame. Here you specify additional data depending on the type of node. The information is displayed like a card index; you navigate between different areas by choosing the tabstrips along the top.
You can display the details for any node by double-clicking it in the left-hand tree structure.
The bottom right frame contains all source fields made available by the data-selection step. These fields make up the source field inventory; you can select from them during the data-mapping process.
