When importing a package, access to the affected links is validated. If you do not have access to a link that is scheduled for removal, the import operation fails, and the associated objects are not marked as Locked for Replication in the target system. An Administrator can modify this behavior by configuring the following property in the Windchill/codebase/wt.properties file:

The default value of this property is false. If set to true, the access check is bypassed. In this case, the import operation does not fail even if you lack adequate access to the link being removed and the associated objects are marked as replicated in the target system.
