Do you mean copying to another sheet? If so, you need to set shared objects in both the document (Settings menu, Document Properties, Server) and the server (QMC, System, Setup, QlikView Servers, expand and click on yours, Documents tab).
Or do you mean exporting? Make sure that the Document Properties, Security tab allows to export objects as well.
Hope that helps.
I mean exporting, it won't let you export when your in Accesspoint, it will allow it if you open the source document in Qlikview but not from the web browser. I have Allow Creation of Server Objects on but I noticed on the publisher server that there is no place to allow the copying of objects?
