Add Constraints
To add, remove, or modify classification constraints, the node must be in edit mode.
The type of constraint you can add depends on the attribute data type. Some constraint rules require no additional data. Other constraint rules need data specified to define the behavior of the constraint. For more information, see Constraints.
1. From the node information page, select Actions > Edit to enter edit mode.
2. Navigate to the attribute information pane and select the Constraints tab.
3. Select one or more constraint types from the list. Use the SHIFT or CTRL keys to select multiple rules. For more information on the available constraint rules, see Constraint Types.
4. Click OK.
A constraint is added to the New section of the Constraints table for each rule selected.
