The minimum and maximum lengths of CN numbers and Reference Designators in Windchill versus Oracle Applications differ. This difference may cause failures when publishing CN Objects fromWindchill PDMLink to Oracle Applications. The differences in field lengths can be characterized for each object type (Parts, BOMs, operation labels, Resource numbers and CNs) handled by Windchill ESI, however, field length limitations need to be set for CN numbers and Reference Designators only, since the maximum field length for these fields in Oracle Applications is less than the Windchill maximum field length.
