After you sign in, ePM presents you with a layout comprising two tabs across the top, a tree view on the left, and a canvas on the right, where you view and modify settings. See Figure 5–3.
Tabs are modal: The display of the panes beneath depends on which tab is active.
Tabs are not “sticky”: When you change modes to a new tab, all unsaved changes in the previous tab are discarded.
The explorer pane on the left displays a hierarchical tree of containers and contents:
When the B2B Host Configuration tab is active, the Host Explorer tree displays B2B Hosts and their contents.
When the Trading Partner Configuration tab is active, the Trading Partner Explorer tree shows Trading Partners and their contents.
There is only topmost node (also called the root node). This is always named “B2B Repository” irrespective of the Repository name.
In the explorer pane, the operation of the New button depends on the currently selected item in the tree: The button is available if and only if you can create a new child object of the currently selected item.
The Delete button deletes the selected object and its children (if any).
The Refresh button discards any unsaved changes and then displays an updated snapshot of the objects in the Repository.
Because many actions in ePM cause unsaved changes to be discarded, any time you add or change a value, it is good practice to verify the change and then click Save.
