How to reference a map

About this task

Use the following procedure to reference a functional map. To reference a map in this case means to "single-source" - or use a map in an external map source file by creating a reference to it.

For maintenance reasons, use this method as an alternative to copying maps. By referencing a map, maintenance can be performed in one location instead of the several locations that you might have copied the map to.
