Creating Constraints
Constraints are conditions defined by you that are applied to selected fields in an Integrity Lifecycle Manager type. The conditions can be used to restrict the values that display in the field, or to make certain fields mandatory when editing an item.
Once you have defined a type, and the corresponding fields for that type, you can create constraints to further customize the display of data in all items for that type. Constraints allow you to:
limit the allowed values that display in a field
define mandatory fields (as defined either on a state or on a constraint)
customize error messages that are displayed to users when an invalid value is selected or when a mandatory field is left empty
You can configure the following categories of constraints: basic, field relationship, rule, or Item Backed Pick List (IBPL).
