Adding a New Constraint
* 
Use caution when adding constraints on attributes, to avoid adding conflicting constraints. If multiple constraints are added to an attribute, then the attribute values must satisfy all of the enabled constraints on that attribute.
To add a new constraint, use the following procedure:
* 
You must be in edit mode to add a new constraint. The new constraint is not persisted until your changes are saved. Click Done to save the changes and return to view mode, or click Save to save the changes and remain in edit mode.
1. View the attribute information page for the attribute to which you want to add a new constraint.
2. On the Constraints tab of the attribute information page, click the add new constraint icon .
The New Constraint window appears.
3. Choose one or more rules from the list. Use the SHIFT or CTRL keys to select more than one rule. Only those rules applicable to the data type of the attribute are available for selection. For more information on the available constraint rules, see Attribute Constraint Rules.
4. Click OK.
A constraint is added to the New section of the Constraints table for each rule selected.
Once the constraint has been added, you can edit the constraint data, as appropriate.
