AutoPLANT with ProjectWise integration, Multi-Project, Document belongs to which project


I'm little confused when using AutoPLANT integrated with ProjectWise.

I copied drawings from one project to an other project. Once done I did the AutoPLANT/Register Document. I'm seeing the document related to the destination project in the doc_reg table.

Now when I attach (overlay) the copied drawing in a 3D model it says that theis drawing belong to the source project.

Info: PSYS0102: The AutoPLANT drawing being xrefed currently belongs to another project XXXX

What should I do and how to know to which project a document is attached?
