Configuring Uniqueness Level
Prerequisite
A site administrator should add the property wt.org.EnforceOrgLevelUniqueness to wt.properties file and propagate it using the Xconf utility. The uniqueness level of an object is determined by the value configured in the property. If the property does not exist during upgrade or migration, by default the uniqueness is set at organization level in the upgraded Windchill system.
Setting the Uniqueness Level
Upgrading to Organizational Level Uniqueness—Set the property to true. This allows the user to create objects with duplicate identities in different organizations.
Upgrading to Site Level Uniqueness—Set the property to false. This allows the user to have standardized single numbering scheme across the site.
