When the OSLC Remote Application is Configuration Management enabled and using a Global Configuration (GC), an additional check-box will be
displayed (checked by default) when selecting Windchill Change Management artifacts. This check-box label is:
Show only artifacts related to the current Global Configuration and as its name says, allows to show only those Change Management artifacts which are associated
to the GC being used  in the OSLC Remote Application. It is highly recommended you keep this check-box as checked so can only link to
"compatible" Change Management artifacts .
When the OSLC Remote Application is Configuration Management enabled and using a Global Configuration (GC), only the Parts that belong to the selected GC will be displayed in the selection dialog.
