Current market conditions drive us to have multiple Organizations based on the type of busines domains like Automotive, Computing and soo on. The file names are either driven by the Customer or by the standard naming conventions. The file names are pretty much same across Organizations but the contents in it like Parameters, Co-ordinate systems, tables, symbols are different between each Organization. So the CAD file is actually different, but having the same name across Organizations is not feasible in Windchill. Hence a property to enable unique file naming constraint at Org levels should be provided. This will help us to have unique file names at site level or at Org level.
