Editing Constraint Data
* 
The following rules apply:
• Only New constraints, constraints that are created on that attribute, can be edited. Modeled or Inherited constraints cannot be edited.
• You must be in edit mode to edit the constraint data. The edited data 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.
Some constraint rules require no additional data. Other constraint rules need data specified to define the behavior of the constraint.
Add, remove, or edit the constraint data in the Data column for the constraint. For details on how the data for each constraint rule is specified, see Attribute Constraint Rules.
* 
Constraints that restrict the allowable values for an attribute only apply if there is a value set for the attribute; if the attribute value is empty, those constraints do not apply.
In addition to editing the constraint data, you can also enable or disable the constraint.
* 
Deleting constraint rule data (for example, removing an entry from a legal value list) also removes that value from the advanced search criteria for the attribute. This is true even if there are objects in the database that include the constraint rule in their attribute values.
