Parent and Child Serialization Rules
Parent rules are rules generated from serialization on an independent business object and component. The serial number that the rule generates is unaffected by the serial numbers that other rules generate. By default, the Case Rule is the parent rule for the serialization rules provided with Siebel Public Sector. For a description of the Case Rule, see About Serialization Rules.
Parent rules can have several child rules. Child rules include serial numbers already generated for the parent rules. For example, the Case Attachment rule is configured so that it begins with the serial number that the Case Rule generated. Its first attribute type is Parent Serial Number. For more information, see Serialization Rule Attribute Types.
