Rules for Using Upload and Checkin
Consider these rules for using Upload and Checkin with iPart Factory objects:
To check in an iPart Factory, you must first save it to a workspace.
If you modified an instance and want to check in the changes, you must check in the generic and all instances.
If a checked out instance was removed from the iPart Factory, then on checkin the system performs Undo Check Out on that instance to remove it from the workspace.
