In Figure 10.2, you can see that the number range is defined by a two-character
code; in this case, the options are 01, 02, 03, 04, 06, and XX. The purchasing user
can enter the code and then define the number range. This cannot overlap with
existing number ranges. You can then define the number range as external by highlighting
the Ext field. If the number range is not defined as external, it defaults
to internal. The user can define the current number of the Vendor Master if the
internally assigned numbers need to start at a certain point.
