Right-click the root node, or on an existing decision node, and select Add Decision as First Child, Add Decision Before, or Add Decision After.
The options that are available depend on where in the decision tree the
node is located. For example, Add Decision as First
Child is not available when you right-click a decision node that
leads directly to a result node. Add Decision
Before and Add Decision
After are not available when you right-click the root node.
If you select Add Decision as First
Child, the new node is displayed to the right of the current
node. If the current node already has one or more child nodes, the existing
children move down and the new node is placed at the top, indicating that its
formula will be evaluated first.
If you select Add Decision Before,
the decision node is displayed above the current node, indicating that its
formula will be evaluated before the current node's formula.
If you select Add Decision After,
the node is displayed below the selected node, indicating that its formula will
be evaluated after the current node's formula.
