1) An external source is used to import an organization tree. i) Each tree node object contains an attribute point(reference) the parent node. ii) Import works fine.2) The tree is synchronized to the metaverse. Tree nodes are joined-projected to organizationalUnit objects in the meta verse. i) The meta verse object has been extended with an attribute memberOfOrgunit (Reference). ii) The synchronization works fine3) An extensible magament agent has been created that exports the orgunit objects to an external application. i) An CS record is defined with an export attribute flow of the memberOfOrgunit of the metaverse. ii)When records are queried in thenthe values have flowed properly into the cs objects. iii) However in the XML assembly no value is available and the .IsPresent property is set to false.Doing some kind of transfer-translation in the provisioning dll is also not an option sine reference values are not exposed.

Not sure I understand what the actual question is.However, you can geta complete overview of how reference attributes work and how they are processed from the Design Concepts for Managing Reference Attributes.Also, if you don't get anything exported, you might wantto take a look at About Exports.Cheers,MarkusMarkus Vilcinskas, Knowledge Engineer, Microsoft Corporation
