About the Cardinality of Child Integration Components
By default each child integration component created in Siebel Tools is assigned a cardinality value of Zero or More. The values Zero or More, or Zero or One, mean that the corresponding integration component is optional. Setting the value to One, or One or More, means at least one integration component instance must be included in the hierarchy. When the cardinality value is set to One, you must have one and only one instance of the integration component in the hierarchy. Table 3 lists possible cardinality values.
